The mod adds a new kind of animal to Minecraft - hamsters. It's a little cute, fluffy creature. At the moment there are eight different colors, as seen on the first image below.
Use hamster seeds (food) to feed them with if you want tot tame one. For some odd reason too, the mod also allow you to have them placed on your head. Not sure how helpful it is to wear a hamster as a hat but it's a fun thing about the mod we should let be known.
Creator: ElSirKael created it for MCPE. P-there-is, Modochu and RazzleberryFox created the original mod for PC.
