>>46939467alakazam and timburr's spoons and wood work because they make sense as a logical extension of the concept and the pokemon's fighting style, and they also don't awkwardly have top put said objects down every single time they fight. And that's to say nothing of the fact that there is no way to fuse those objects with the designs without it looking awkward or just unfitting.
gorillas literally already do the thing that rillaboom needs the massive drum to apparently do. by your very definition doing the exact same thing as a real gorilla- drumming- should make it just as much of a cartoon animal, but I suppose if it's doing it in a more arbitrary and inconvenient way instead of turning the pokemon itself into a sort of living drum, that makes it "boring"
>It attaches to its back. Doesn't seem awkward at all.the drum acting as a hair pin is like a tiny piece of duct tape on a glaring hole in the design. Hell, the drum shouldn't even function properly if it has a big enough hole in it for Rillaboom to squeeze all of it's hair into it.
