So i'm pretty sure you all know these lovable (or scary) inflatable dudes:
So my point is, Illoai could get a silly skin when she flail around these dudes instead of tentacles.
Passive: The tentacles are the Wacky waving inflatable arm flaling tube men
Q- Smash down one of this wacky dude.
W- Some silly effects on it
E- Silly effect
R- I guess kinda like a surprise party effect.
As far as she looks, i have no idea, but i guess it needs to be kinda stupid looking. Liek suprise party amumu and fiddle.
