And then Yoshi's tongue flies in from the side of the screen and knocks Blooper off. Yoshi walks in and it becomes Super Yoshi Galaxy!
OK, I'm joking.
Super Blooper Galaxy hey. Well, Blooper is a squid/jellyfish so wouldn't all the worlds have to be water worlds, unless of course Blooper could float in space. He could have a spin move where his tentacles all spin out to the side making him bigger, therefore making it easier to attack something. How would something attack Blooper? You can't come up at him from underneath; he'd sting you, and since he's underwater, a bonk on the head wouldn't so much.
