I think the whole “entertainment spell” thing works really well for Spider with a Top Hat as a potential trans allegory.
How when SwaTH tried to show the Narwhal he could be a fighting spell too, the Narwhal just laughed at it… and he wasn’t even trying to be mean; he really thought it was a joke. But that didn’t make it feel any better.
Basically whenever SWaTH tried to do anything for himself, anything genuine, it was seen as a joke by everyone around him & that is symbolized in the idea drilled into him that the entire purpose of his existence is to be a joke to others.
Which is not unlike the treatment of trans people in a lot of media and especially cartoons.
