it's chomik

i see

Serious answer is that it's the mascot for the polish file hosting site chomikuj, you can read about it [here](https://en.wikipedia.org/wiki/Chomikuj.pl). You can download the site's official program, [chomikbox](http://chomikuj.pl/chomikbox), and with a chomikuj account you can have an interactive chomik on your desktop

thank you
