SpongeBob vs Kirby

Description
Nickelodeon vs Nintendo, which of these two childish, cute and lighthearted powerhouses with a malleable body will win in a battle to the death?

Interlude
'''Boomstick: Life tip number one: Don't judge a book by it's cover. People might look cute on the outside, but inside they could be your doom.'''

Wiz: Such is the case with Kirby, Nintendo's pink puffball of happiness and dreams.

Boomstick: And SpongeBob SquarePants, Bikini Bottom's annoying and childish resident, and savior of the world!

Wiz: Just to be clear, SpongeBob will have access to his magical page.

Boomstick: He's Wiz and I'm Boomstick!

Wiz: And it's out job to analyse their weapons, armour and skills to find out who would win a Death Battle.
