Meowser

Meowser is the name used for the Cat form of Bowser introduced in Super Mario 3D World. Bowser obtains the form once, in the final battle sequence of World Bowser-Castle: The Great Tower of Bowser Land. He has white and orange fur with brown stripes, similar to a tiger's, a ringed tail, cat ears instead of horns, whiskers, and his nose is black. Also, his hair is colored red, white and brown, and his shell appears to become more gray-blue, looking similar to Dry Bowser's (but without red gaps). Even his trademark roar becomes different, giving off more of a meow-like sound. Like Cat Goombas and Cat Bullet Bills, the form is more akin to a transformation than a suit. The name is a portmanteau of "Bowser" and "meow", the onomatopoeia for the sound that a cat makes.

The form makes its only appearance in the final section of The Great Tower of Bowser Land, as he uses the form in an attempt to fight Mario and his friends. Like Cat Mario, Meowser can climb walls and swipe his claws at his enemies. Unlike Cat Mario, however, his tail is large enough to whip, like Tanooki Mario, as well as retaining his ability to breathe fire (though he uses this less often). After Mario and his friends attack him with a POW Block, Meowser uses the power of Double Cherries to become Double Meowser, spawning up to five doubles to fight them. The player cannot harm Meowser directly; the only way to finish the fight is to hit the giant POW Block four times at the top of the tower to defeat Meowser. The Clear Pipe to the Goal Pole will then be revealed.

The final boss battle against Meowser is reminiscent of the final boss battle against Wario at the end of Super Mario Land 2: 6 Golden Coins, where the final boss uses power-ups against the player.
