Blot is a Mime, so he is preforming imaginary Stuff, such as Invisible walls, or pulling Invisible ropes.

Yatta is going crazy! She's doing cartwheels and whatnot while dropping candy all over the stage as the crowd cheers and applaud.

Looey is preforming like any clown would in a Circus.

(Rremember Blot speaks backwards. It's okay if you don't wanna do that because it's kinda hard to understand, I'm just saying it'd be more accurate if you did :D )
