Boss Calvawash 1.0.0

--IF--

WARNING: She sings too well.

A somewhat unique boss character.
It is probably one of the most difficult bosses to fight, since it has a lot of health and requires either strategy or insane attacks.
It cannot be affected by F1, I think.
If you defeat her, in the next round she will not be there and you'll automatically win. You only have to win the first round.
Here is a demo: 

How to defeat her:
Characters with a lot of damage or who can dodge (for example, the multiple variants of Warner's Luigi).
Small Characters (Pocket Characters like Pocket Metal Mario).
Cheap characters (Ketchup Donald).
Or just learn Uncle Joel's attacks and use them smartly (punch x3, Y + B and D, DF, F, A + B).
