Green outline

This Mouse has a light green outline, meaning you can eat it.

Outlines are a feature in Animals you can eat have a light green outline, and animals that can eat you have a red outline, and often with a green area to bite the animals tail. You and other animals that are too far away from your current tier to either eat or be eaten by you have a dark green, blue, or gray outline, depending on if you are on land, water, or the arctic.

This Mole has a red outline, meaning it can eat you!

No outline

This Elephant has a blue outline, which means you are in the water and neither one of you can eat each other.


  • On March 14, dark green outlines in Ocean were changed to blue and dark green outlines in the Arctic were changed to gray. Land animals have a Dark Green Outline.
  • Outlines used to be in the older logo of as if Pike's old logo used to have a red outline for the dragon and a light green outline for the mouse, but that was fixed in the final logo, since Dragons can't eat mice!
  • Food also have outlines to tell if it's edible or not, but food never has a red outline. (Food can't eat animals, that would just be weird!)
    • However, ducks can eat you... but they are AI animals, not food.
