Galactic warador is the closest I could get to a court jester, which is what I always imagined Peeves in Harry Potter to look like~ Anyone have a better idea?

I think that suits him really well, and I'd definitely stick with some kind of warador. A couple other ideas: I like that the nightmare looks like it's laughing, but that's the old pet design and will likely get updated soon (maybe this month, actually, it's NM season). Reborn's got a similar tone but the blatant fire isn't suuuuper Peeves-y. Storm's just kind of a nice overall warador.

I think the Nostalgic Warador is definetly fitting!

But I also enjoy the idea of a Nightmare Warador as already mentioned.

Maybe the Scribble? Reborn & storm are awesome ideas.
