The map

The 12 biomes of the corridor

The Steal An Egg map is one straight line starting at your base. Each biome has its own guardian, its own animals (8 per biome; 16 in Angels & Demons, plus 2 fusions) and a recommended speed.

Speeds from the community wiki; in the game, a sign at the entrance of each biome shows the recommended speed. A big egg slows you down: plan for more speed than recommended.

Your base and the safe zonestart of the corridor

Forestbiome 1

Speed: none needed8 pets

The starting point, right after the safe zone. No speed required: this is where you steal your first eggs, watched over by a sleeping chicken.

Lakebiome 2

Speed: 9008 pets

The first biome that needs speed. It has eggs from both land and water animals, guarded by a swan.

Desertbiome 3

Speed: 10K8 pets

Sand as far as the eye can see, and a pyramid. Eggs are already worth a lot more than in the Forest, and the scorpion never lets go.

Junglebiome 4

Speed: 40K8 pets

A thick forest full of fierce animals. The tiger guarding the nests is fast: have some speed to spare.

Snowbiome 5

Speed: 170K8 pets

A biome covered in snow and ice. The yeti sleeps next to the nests and wakes up as soon as you steal an egg.

Volcanobiome 6

Speed: 700K8 pets

Lava, magma and scorching rock. The eggs pay well here, but Cerberus comes after you as soon as you take an egg.

Abyss Oceanbiome 7

Speed: 2.5M8 pets

The bottom of the ocean. A cave in the left wall hides Nibbles (Experiment #013), who starts Dr. Scramble's secret quest.

Prehistoricbiome 8

Speed: 18M8 pets

The land of dinosaurs. The T-Rex guards huge eggs: the bigger the egg, the slower you run back.

Cosmicbiome 9

Speed: 700M8 pets

A purple floor under a starry sky, home to creatures from another world. This is where you find the egg of the Unicorn, the first Divine pet.

Cherry Blossombiome 10

Speed: 2.5B8 pets

A Japanese garden with a torii gate at the entrance and petals in the air. Added in Update 1.

Titan Templebiome 11

Speed: 7B8 pets

A rainforest where the sacred temple of the Titan stands, guarded by the Gorilla King. Added in Update 2.

Angels & Demonsbiome 12

Speed: 20B18 pets

The end of the corridor. At night the biome can turn into the Angels side or the Demons side, and sometimes into a secret merged version of both that gives extra luck. A secret shrine hides behind the waterfall.
