My Derp is a game with a unique and funny story, where you play to take care of the new pet, Derp. It is a very difficult task, as Derp is a very yucky and sickly virtual pet, so the first thing you need to do is to feed him and make him healthy. In the process, you will also have to deal with a lot of obstacles and try to keep him alive.

Feed him the right food and make sure he gets all the necessary nutrients.

The game also includes a mini-game and earn coins to buy supplies.

After making him healthy, you can also unlock the different shapes he can take.
