Clubosaur

A Clubosaur is a triceratops-like enemy that Wario encountered in Wario World. As its name implies, it stands on its hind legs and wields a club. At any time, the Clubosaur may charge up and go on a rampage, swinging its club frantically. The Clubosaur is invincible in this state, but the attack doesn't last very long. The club also blocks all frontal attacks, so Wario needs to sneak up on a Clubosaur from behind.

After enough punches, the Clubosaur loses the club and reverts to standing on all fours. Now the Clubosaur may charge at Wario, a more powerful attack that leaves him immobile for a few seconds.

Other varieties of Clubosaurs include Skelosaurs, Gatorbabies, Polar Bears, Grizzlies, Masked Clubbers, and Club Mummies. Aside from a few costume changes and choice of club (the Polar Bear uses an icicle, for example), these enemies behave in exactly the same way as Clubosaurs, though they do get progressively more aggressive.
