Mr Whiskers

 is the boss of Wonchubeemee Mine Part 1.

Attacks
The oversized, cybernetic walrus is a difficult enemy, as he has plenty of attacks and is quite agile for such a giant beast. By far his most devastating, but easy to avoid attack is the splashdown, with his tail. Other include laser attacks and, of course, support from the ever-present zombies.

Strategy
Stay on the move, keep attacking. The walrus takes a while to defeat, but isn't as powerful as the Beelsteambub.
