Kirby is a series of video games by Nintendo, and later an anime cartoon was produced based on these games (which was dubbed by 4kids, in what is widely considered one of their few good dub jobs). Kirby is a small, pink blob with an endless appetite and the ability to copy the abilities of enemies he swallows. He also has a sunny disposition and a strong desire to help people in need, though there are theories out there that he is in fact nothing less than pure destruction incarnate.

Kirby minis are mini-Krackos.
