Blooks
A Blook is Blooket's collectible character, small animals, food, humanoids and creatures that you use as your in-game avatar. There are eight rarity tiers and 287 Blooks across them. This page walks the tiers from most common to most rare. Start here if you're new, or jump straight to Legendary, Chroma, or the Rarest ranking.
The two pack-tier deep dives, every Legendary and every Chroma, cover the chase tiers in detail. The rarest blooks ranking combines all eight tiers into one ordered list. For per-Blook chase math, the chase calculator covers every Legendary, Chroma and Mystical, and the broader blooket calculator turns any drop rate into a token budget.
How rarity actually works.
Every pack roll is independent. The game picks a tier first using the pack's tier weights (e.g. Safari Pack is 66% Common, 30% Rare, 3.48% Epic, 0.5% Legendary, 0.02% Chroma), then picks one Blook within that tier. That's why a pack with two Legendaries splits its tier rate between them, and why a pack with a single 0.03% Chroma is mathematically rarer than a Legendary.
Tier matters more than name. A "Legendary" in one pack can be 10× rarer than a "Legendary" in another, because the tier rate is set per-pack. The eight cards below give the practical band, what to expect across the catalog.

Cards with their own page link to a dedicated breakdown. Tiers without a page are covered inside the Value Guide or the Rarest ranking, links are inline.
The free starter tier. You unlock most of these in your first week of casual play, and a couple come pre-bound to your account before you ever spend a token.
The biggest tier in the game. Wonderland, Bot, Dino, Breakfast, Lunch and the seasonal packs lean on Uncommons as their bulk drops.
The last 'open enough packs and you'll get one' tier. ~100 packs generally clears the full Rare set per pack family.
The transition tier. Epics resell for more tokens than a 20-token pack costs, so they're net-positive to open even when you whiff on the Legendary.
The chase begins. King is the most generous (1%); Mega Bot is the rarest standard Legendary at 0.03%. Expect 150 – 2,300 packs to reach a 50% chance.
Rarest tier obtainable through normal packs. Seasonal 100%-Chroma windows (Lovely, Lucky, Spring) are the fast lane around the bad math.
Wise Owl (ISTE 2023 Live in Philadelphia) and Wise Caterpillar (Khanmigo signup). One-time event drops; nobody will ever pull these from a pack.
Animated trophy Blooks from contest leaderboards. Tim the Alien, Spooky Ghost, Phantom King, Rainbow Astronaut, Hamsta Claus. The actual rarest tier in the game.
The rarest 10 Blooks in the game.
Five Mysticals, three Chromas, two Legendaries, ranked by community estimates of obtainability, not raw drop rate.
Tim the Alien → Mega Bot, the top-10 ranked.
Tim the Alien (Mystical, Pokemon Are Cool 1st place) sits at the top. Mega Bot (Legendary, 0.03%) closes the list. Every entry shows the obtainment path, pack, event, contest, and the chase math when there's a calculator behind it.
