i imagine that chara likes to tap dance, though im not sure how that would transfer. i think they have pretty good control of their body though, and decent balance (as a kid at least, when they hit their teens they’re kind of a fucking mess). so they could probably manage. falling would piss them the fuck off though heh
asriel wouldn’t be any good at it, but he keeps doing it because it’s fun, and he’s so fat and fluffy anyway that falling doesn’t really hurt at all. he kinda likes falling after getting a lot of momentum because then he slides.
