Most of this is gut-busting hilarious, super dark humor played as cartoony silliness, but then it suddenly gets really transphobic right at the end in a way that is plot-vital and pretty gross. Probably not worth your time or anyone else's.
I know humor has changed a lot in the past few decades; there's some jokes in Dr. Slump that couldn't possibly fly past even the most lenient radar nowadays, and sometimes that makes it even funnier. But Even in 1994 this wasn't OK. I love me some Akira Toriyama comedy, but there is plenty more of it that doesn't involve outright hateful gags.
