It's a polar bear named Beartosz I drew for my simple game project. He was supposed to look possibly nice and child-friendly. This game should be playable by kids and be possibly educational so a silly little Beartosz is a better main hero than Beartosz the Seal Devourer. ; P
His name's modified version of name Bartosz used in Poland (and maybe other countries). The "sz" is read like "sh".
In case anyone cares - that game's gonna be really simple and I'm most likely not even going to publish or share it anywhere (I'm just learning how to use Unity3D this way so this project won't be worth much. It's all about running, gathering fish and avoiding obstacles).
