What Are Hidden Blooks in Blooket?
Hidden Blooks are rare, special-access collectibles in a separate section at the bottom of your Blooks page. A unicorn banner marks the section, and each blook stays grayed out until you earn it through its own method. The community also calls them secret blooks.
These blooks never drop from the standard Market packs you open every day. Each one ties to a pack, an action, or an event. They add to your Blook Score but give no gameplay advantage, so they work as pure status symbols.
The five types follow separate rules. Knowing the type tells you the method, the cost, and the bigger question of obtainability. We break down every Chroma against Blooket's published rates in our guide to how Blooket odds work, so you chase the right pack instead of guessing.
What Are the 5 Types of Hidden Blooks?
Hidden Blooks split into five types: Chromas (84, pack-based), Uniques (2, action-based), Mysticals (5, event-based), Admin (server-side), and Unreleased (datamined). Three reach players: Chromas through packs, the Wise Caterpillar through a free action, and Mysticals only when an event returns.
The table below maps each type to its method, count, sell price, and Blook Score. Use it as your quick reference before you spend time or tokens.
| Type | Count | How to Get | Sell Price | Blook Score | Obtainable 2026 |
|---|---|---|---|---|---|
| Chroma | 84 | Open the right pack | 300–6,000 tokens | 25–50 | Yes |
| Unique | 2 | Free action (Khanmigo) | 300–500 tokens | 10 | Wise Caterpillar only |
| Mystical | 5 | Win a Blooket event | 1,000 tokens | 75 | No (retired) |
| Admin | Server-side | Granted by staff | Not sellable | Hidden | No |
| Unreleased | Variable | Not released | Not sellable | Hidden | No |
Chromas
Chromas are color reskins of standard blooks, tied to specific packs. They form the largest hidden group at 84 total, with pack drop rates from 0.01% to 0.08%. A few seasonal packs guarantee a Chroma after a token threshold, so timing beats luck in those windows.
The Ice Monster Pack gives the best odds anywhere. It holds three Chromas at once, Ice Slime (0.08%), Frozen Fossil (0.05%), and Ice Crab (0.02%), a combined 0.15% per opening, roughly five times any other pack. The Rainbow Panda sits at the floor, dropping from the Safari Pack at 0.02%.
Uniques
Uniques number exactly two: the Wise Caterpillar and the Wise Owl. The tier sits above Chroma by classification, yet one of the two costs nothing and takes minutes.
The Wise Caterpillar stays free and obtainable for every account through a Khan Academy action. The Wise Owl went to attendees of one 2023 conference booth and now sits retired, so no method brings it back.
Mysticals
Mysticals are the rarest tier in the game, awarded only to top finishers in Blooket-hosted events. Five exist: Spooky Ghost, Tim the Alien, Phantom King, Rainbow Astronaut, and Hamsta Claus.
Each sells for 1,000 tokens and adds 75 to your Blook Score, the highest in the game. Tim the Alien holds the rarest crown, with only two known owners from a tied first-place finish.
Admin and Developer Blooks
Admin blooks come straight from Blooket's development team. No event, pack, or action reaches them, and they stay invisible until staff grant one directly. Any tool promising an Admin blook lies, because Blooket assigns these server-side.
Unreleased and Scrapped Blooks
Unreleased blooks exist inside Blooket's files but never reached players. They surface in community datamine leaks, which feeds the flood of fake "how to get" videos online. No method earns one until Blooket releases it, and some never ship at all.
How Many Hidden Blooks Are There in Blooket?
Blooket holds 91 confirmed Hidden Blooks across the named tiers: 84 Chromas, 2 Uniques, and 5 Mysticals. Admin and Unreleased blooks add an uncounted extra layer. Blooket publishes no official total, and the number climbs with each seasonal pack and event.
The breakdown stays useful even as the count moves:
- Chromas dominate by volume and remain the only group you chase reliably with tokens
- Uniques and Mysticals stay tiny by design
- Admin and Unreleased blooks stay locked for every regular player
Seasonal events add new Chromas every year, so the in-game Hidden Blooks section always shows your current total. We track each addition against Blooket's pack rates and update our Chroma database as packs rotate.
How Do You Get Hidden Blooks in Blooket?
Your method depends on the type. Chromas come from opening the correct pack, the Wise Caterpillar comes from a free Khan Academy action, and Mysticals come from winning a live event. Token grinding supports pack openings but earns no hidden blook on its own.
How to Get Chromas (Open the Right Pack)
Chromas drop from one specific pack each, never from random openings. The table below maps the headline Chromas to their pack and verified rate.
| Chroma | Source Pack | Drop Rate |
|---|---|---|
| Ice Slime | Ice Monster Pack | 0.08% |
| Frozen Fossil | Ice Monster Pack | 0.05% |
| Red Astronaut | Space Pack | 0.05% (rotates by weekday) |
| Teal Platypus | Outback Pack | 0.03% |
| Rainbow Panda | Safari Pack | 0.02% |
| Ice Crab | Ice Monster Pack | 0.02% |
| Elf Sweater Snowman | Blizzard Pack | 0.01% |
A 0.02% rate means roughly 3,500 packs for a coin-flip chance. More openings raise your probability, yet no count guarantees a pull. Before you spend a single token, run your exact odds in the calculator and see your true chance at any token amount.
How to Get the Wise Caterpillar (Free)
The Wise Caterpillar is the easiest hidden blook in the game and costs zero tokens. You claim it by saving a Khanmigo-generated set to your Blooket account through the Khan Academy partnership. The whole process takes about five minutes.
Open Khan Academy's Khanmigo Blooket Generator, create a question set on any topic, then save it to Blooket. The Wise Caterpillar appears in your Hidden Blooks section within seconds. Our step-by-step Wise Caterpillar guide covers every screen plus the fixes when it does not show.
One catch trips up new players. The Wise Caterpillar shares the Wonderland Pack art, so people hunt for it in packs. No pack contains it, and chasing one wastes tokens.
How to Get Mysticals (Win an Event)
No Mystical reaches players in 2026, because every original event has ended. Spooky Ghost, Tim the Alien, Phantom King, Rainbow Astronaut, and Hamsta Claus all came from limited contests like the Contest of Candy, Pokémon Are Cool, and the LUNCH event. A new Mystical appears only if Blooket runs a future event with one as the prize.
Tokens cannot buy a Mystical, and account sharing transfers nothing. The prize stays locked to the account that earned it.
How to Grind Tokens for Pack Openings
Token grinding fuels Chroma chasing, not a direct hidden-blook drop. Build your reserve first, then open during the right pack window. Café and Tower Defense return the most tokens per session, while Gold Quest suits quick classroom rounds.
Stack your tokens before each seasonal pack opens. The Lovely, Lucky, and Spring packs guarantee a Chroma inside their short annual windows, so a loaded reserve beats raw luck.
Which Hidden Blooks Are Still Obtainable in 2026?
Two routes stay open in 2026: every pack Chroma, and the free Wise Caterpillar. All five Mysticals, the Wise Owl, every Admin blook, and all Unreleased blooks sit unobtainable. Status moves with each update, so confirm in-game before a long grind.
| Blook | Type | How to Get | 2026 Status |
|---|---|---|---|
| Rainbow Panda | Chroma | Safari Pack | Obtainable |
| Ice Slime | Chroma | Ice Monster Pack | Obtainable |
| Ice Crab | Chroma | Ice Monster Pack | Obtainable |
| Elf Sweater Snowman | Chroma | Blizzard Pack (seasonal) | In window |
| Wise Caterpillar | Unique | Khanmigo set (free) | Obtainable |
| Wise Owl | Unique | ISTE 2023 booth | Retired |
| Tim the Alien | Mystical | Pokémon Are Cool event | Retired |
| Rainbow Astronaut | Mystical | LUNCH event | Retired |
Retired blooks need their original event to return. Once Blooket ends an event for good, the linked Mystical closes with no workaround.
When Are the 2026 Blooket Events for Hidden Blooks?
Blooket's hidden-blook events run on a seasonal calendar. Lovely Pack opens around February 14, Lucky Pack around March 17, Spring Pack in late March, Spooky Pack in late October, and Blizzard Pack in December. The Mystical events stay retired with no 2026 return announced.
| Event / Pack | Window | Tier | Status |
|---|---|---|---|
| Lovely Pack | Around February 14 (4 days) | Chroma | Annual |
| Lucky Pack | Around March 17 (4 days) | Chroma | Annual |
| Spring Pack | Late March to April | Chroma | Annual |
| Spooky Pack | Late October | Chroma | Annual |
| Blizzard Pack | December | Chroma | Annual |
| Contest of Candy | Late October to December | Mystical | Retired |
Plan your token reserve around these dates. A short window plus a guaranteed seasonal Chroma rewards players who prepare early.
Why Don't Blooket Scripts and Hacks Work?
Blooket scripts and hack tools fail because Blooket validates every blook server-side. Console code, GitHub unlockers, and browser extensions cannot grant blooks, and accounts caught using them face suspension or a permanent ban. Many of these tools also carry malware that steals login data.
- Console scripts do nothing lasting. Visual changes vanish on refresh because the server never recorded them.
- GitHub "unlock all" repos either fail outright or harvest your credentials.
- Extensions promising free tokens or Admin blooks often install trackers, and Admin blooks stay server-side regardless.
- TikTok "I got Tim the Alien" clips are edited or use temporary tricks that never save.
If a guide tells you to paste code into your browser, open a GitHub link, or install an extension, stop. The only safe path runs through Blooket's own in-game methods.
Common Hidden Blook Problems (and Fixes)
Most hidden-blook issues trace to display lag or the wrong expectation. The Wise Caterpillar usually appears within ten seconds, pack pulls credit server-side even after a crash, and event prizes sometimes need a support ticket.
- Wise Caterpillar did not appear. Refresh your dashboard and recheck the Hidden Blooks section. It lands within seconds of saving the set.
- Pack opening crashed mid-roll. Refresh and check your collection. Blooket credits the pull on its servers even when the animation breaks.
- Section looks empty after a Chroma pack. Confirm you actually pulled the Chroma. Low rates mean most openings show only Common to Legendary blooks.
- Event prize missing. Open a Blooket support ticket. Event credits sometimes lag and need manual review.
