Planet Punk

Planet Punk is the planet to which all of the enslaved hares of Warren were taken by the Toad Empire, and forced to build a climate converter. The planet was liberated by Bucky O'Hare and his crew, and the finished climate converter destroyed before it could do any real damage to Punk.

Punk is, arguably, the game's version of the planet called Kinnear in the cartoon, and the biggest evidence against the canonicity of the game. However, it is possible that Kinnear and Punk are two different planets, and the hares were simply captured and taken away to build climate converters twice.
