>>48984657Meowth dresses as humans because it’s funny to see an obvious cat monster dressed as a human. We know what humans look like, and we know that Meowth doesn’t look like one. It’s not the same when Jessie the human dresses as a Pokemon which hadn’t even been shown yet.
It also didn’t sound cutesy and cartoony like that Ivysaur you showed. It sounded like a woman, like they told a voice actress to just say “sana sana” as if it was a person saying it.
Their inclusion in the humanlike egg group is meaningless, most likely done to make them seem cuter. They’re taking the reverse path from what you’re suggesting. Now when Jessie dresses as a gardevoir, she’s in a full body mascot outfit. Now when gardevoir talks, it talks in a silly high pitched voice. They WERE presented as a relatively humanlike Pokemon, now they aren’t.
