Slime Lab is a virtual pet simulator for mobile where you can care for, race, and customize your very own pet slime. Slimes can be a rainbow of colors and can change shape to grow different animal parts, like cat ears or a dog tail, which we call 'mutations'. Besides changing the slime's appearance, these mutations also help your slime perform better in races across five different types of terrain. If your slime wins these races, you win Goo (the game's currency) which can be spent to acquire more mutations. It can also be spent on new items to help care for your slime. Like all pets, slimes enjoy attention and will gladly let you pet, feed, and shower them. You know what they say - a happy slime is a fast slime!
