What is the rarest blook in Blooket?

The quick answer

The rarest blook in Blooket is Tim the Alien. It is a Mystical-tier blook that Blooket awarded to the only two players who tied for first place in the Pokémon Are Cool global event. Community-tracked records put its copies at 2 known owners — nobody has ever obtained it from a pack, because no pack can produce a Mystical at all.

A quick note on sources before the deep dive: Blooket does not publish official blook totals, owner counts, or drop-rate lists. The figures below come from long-standing community trackers (the Blooket wikis and drop-rate calculators) and are labeled as community-tracked throughout. Where numbers conflict between trackers, we say so.

How the Blooket rarity system works

Every blook belongs to a rarity tier, and the tiers define what a “rare blook” even means. The seven standard tiers work like this:

Community trackers count roughly 300–330 blooks in the game — there is no official total. Community wikis also track a Unique tier above Mystical’s neighbors: blooks awarded for unique actions rather than pack pulls. The Wise Caterpillar lives there, and it has its own guide because it is the one “ultra-rare” blook nearly anyone can still claim — see our Wise Caterpillar unlock guide.

All 5 Mystical blooks, ranked by rarity

Mysticals are the top competitive tier: Blooket awards them to top finishers of limited global events, and every event that produced one has ended. All five are animated, and community trackers list them at 75 Blook Score and 1,000-token sell value each.

Owner counts are the community’s estimates — Blooket has never published them. Spooky Ghost is worth a caution: it is not the Legendary Ghost from the Spooky Pack. The pack version is a different blook with a live drop rate; the Mystical Spooky Ghost was a Contest of Candy prize and left with that event.

What is the rarest chroma in Blooket?

For practical collectors this is the more useful question, because Chromas are the top tier you can actually still pull. Fan-measured figures put the rarest currently obtainable Chromas — Rainbow Panda, Ice Crab, and Chilly Chameleon — at about 0.02% per open, or 1 in 5,000 packs. The previously rarest Chroma, Elf Sweater Snowman at around 0.01%, retired from its seasonal home in late 2024. Treat all of these as labeled estimates: the live number is whatever appears in each pack’s preview in your Market.

The rarest Legendary sits between those worlds: community figures commonly cite Aquatic Pack’s Megalodon near 0.2%, while other trackers list Bot Pack’s Mega Bot near 0.03%. The honest answer is that trackers disagree and odds vary by pack — check the preview before planning your grind.

Can you still get a Mystical in Blooket?

As of right now: no. No pack drops Mysticals in any tier, and every event that awarded one has closed. What could change this: Blooket has re-run events and added new event formats over the years, so a future global event could introduce a new Mystical (the Contest of Candy cycle itself changed its Mystical from Spooky Ghost to Hamsta Claus, which proves the slot rotates). The practical move is to watch the event announcements in your dashboard the moment a seasonal event goes live — the top-placing prize is never announced early.

How to actually get rare Blooks (the realistic plan)

1. Know the odds before you spend. Every pack preview shows the odds for its lineup. A 0.02% chase is a long-term project, not a weekend — plan with our pack-odds calculator.
2. Max the daily cap first. 500 tokens plus the Daily Wheel, every day, is the whole economy. More on that in the Market guide.
3. Focus event packs during events. Seasonal packs carry the chase tiers; saving tokens ahead of an event is how collectors catch them.
4. Watch for global events. Competitive events (the Mystical route) are announced in-app. Top placements are brutal, but they are the only door to the rarest tier.

Rarest-blook myths, and what never works

Searches promising “rare blook generators” or hacks that “unlock Tim the Alien” are the same-old scam pattern wrapped in rarer bait: no site can add a blook to your collection, because collections are stored server-side. Our honest hacks guide covers the whole scam family, and the bot guide covers the flood-tool version. The only legitimate route to rare blooks remains: play, earn, and spend with the odds in view — the Blooket help center keeps the earning rules that make that possible.
