Who or what is the Ugliest Mario character?

No, that's the result of Barney's gay marriage with :yoshi:
 
We don't even know if Yoshi is male because it lays eggs.

IDK why you people find Yoob ugly.
He's just a slight redesing and recolor of Yoshi.
Many other characters have claws,
many other characters are massive,
many other characters are fat.
Do you call them ugly?
Er...No.

Why? Because it is a YOOB!
Yoshis are cool because they're small and awesome. Bowser's got some brawn to keep him too ugly. Waluigi's an elf. 'Nuff said.
But Yoobs are Yoobs! And Shroobs are Shroobs! That's why!

It's probably the manboobs or the Barney color scheme doing it (or both).
