-Pachirisu's, Galvantula's, and the Tynamo line's categories are really strange to me. "EleSquirrel?" "EleSpider?" "EleFish?"
I think for Pachirisu Electric Squirrel probably wouldn't fit on the screen or something, but that's just me guessing.
Also Seadra being the "dragon" pokemon isn't that hard to believe. Seadra literally has -dra in its name, so.

Anyway, Mew being the New Species Pokemon is just stupid. It's definitely not a new species by any means.
Caterpie being the "worm Pokemon" when it's clearly a Caterpillar, clearly stated in its name.
Ratatta and Raticate being the Mouse Pokemon after generation iii, which is stupid. It's a rat, not a mouse. Rats =/= mouse, they are completely different rodents.
Sandshrew and Sandslash being "Mouse Pokemon" too, that doesn't look like a mouse to me. Sandslash especially not.
Furret's isn't "the worst" but I find Long Body Pokemon to be a little silly.
Ledyba and Ledian being the Five Star Pokemon when they have no stars to speak of on their body. Where did this classification even come from?
Politoed being called the Frog Pokemon when it's called PoliTOED it is not a frog, it's clearly a toad. It's right there in the name. Frog =/= toad, they're similar but they're not the same animal at all.
Girafarig as the Long Neck Pokemon when it has doesn't have that long of a neck, if you ask me. But, I can forgive this one.
Numel being the Numb Pokemon doesn't make sense to me. This one just comes to me as a strange one.
Happiny being the "playhouse Pokemon" I think this one shouldn't be one word, it should be two. It just feels mistranslated to me, I don't know. I a playhouse is an object, there should be a space in between play and house so it's a verb instead of a noun. That's just a nitpick, though.
Froslass being the Snow Land Pokemon is just an odd one to me. Feels like a poor choice of wording.
Buzzwole being the Swollen Pokemon is weird, but it's a ultra beast so it doesn't really matter, I guess.
That's it, though, I skipped the ones other people already said,
