The game's history since launch, update by update. Updates come out on Saturdays, around 3 PM UTC.
Right now
Every 30 minutes, Rifts open on the map (Overlord boss) and Dr. Scramble's drones invade it. At night, the last biome can turn into the Angels side or the Demons side.
Update 5 · September 19, 2026
Dr. Scramble (Sammy is Coming)
Every 30 minutes, Dr. Scramble's drones invade the map: destroy them to collect Samples.
Spend Samples in the Experiment Shop on the Scrambled mutation (10% chance to work), the Experiment #001 Egg, the Nibbles #013 Egg and boosts.
Secret quest: Nibbles (Experiment #013) hides in a cave in the Abyss Ocean. Gather the 5 parts of the Stolen Experiment Vault to earn the Scrambler bat.
No official end date: according to the game's notes, Dr. Scramble will return.
Update 4 · September 12, 2026
Angels & Demons
A new biome at the end of the corridor: at night it can turn into the Angels side or the Demons side, with 8 animals on each side.
Sometimes a secret merged biome appears instead: it mixes Angels and Demons and gives extra luck while it lasts.
A secret shrine lets you fuse Pegasus and Skeleton Horse into Equinox, and ArchAngel and World Burner into Aetheron.
The Luminous Egg replaces the Monster Egg, a new treadmill and trail arrive, and your base can hold one more pet.
Update 3 · September 5, 2026
The Rifts
Every 30 minutes, Rifts open on the map: go in, beat the Overlord and earn Boss Tokens.
The Boss Shop sells boosts and a mutation shard with a 10% chance to apply the Fractured mutation.
The more you beat the boss, the rarer the rewards you unlock (boss mastery), including pre-fractured eggs.
The lobby Rift trades 3 pets for an exclusive egg.
Update 2 · August 29, 2026
Titan Temple
A new end-game biome with 8 new animals, including the Gorilla King and the Nightflame.
The Monster Egg arrives in the Robux shop, with a rare Mecha version of each monster.
Hungry Frog event: bring infected eggs back to your base and feed their parasites to the Hungry Frog to earn Monster Chests.
Update 1
Cherry Blossom
A new Japanese biome with 8 animals, including the Kitsune (Divine).
The Sakura Incubator: hatch a Crane, bring it to the ancient sakura tree and unlock the Bloom and Spirit Bloom mutations.
The Great Bloom fills the biome with Sakura crystals to break.
