I hear humans are still voicing them so we’re not there yet
The Green Blob may well speak a language that only one of the characters can understand (Possible R2D2 role?):
Blob: "Gurgle, Chirp, Tweet, Gurgle, Whistle"
Another crew member: "He said, 'Janeway's in trouble near the rocks!' "

I think if Okona appeared in Priodgy, that would have to be toned down, that wouldn't really fly in a Nickelodeon cartoon. If he appears in Lower Decks, that can aspect can remain.
If he were to try and put the moves on Mariner, Captain Freeman would order him shot out an airlock.
