I mean in that case it would be Ursaluna, not Kleavor.
I mean for a Bug Signature Pokemon. Right now her options are Lokix, Spidops, and Rabsca. Spidops just isn't good, Rabsca is not a Pokemon you want in a kitchen (or at least its prevo), which just leaves Lokix which is alright though compared to other Pokemon is lacking. So my joke was her trying to get the Kleavor categorized as a Gen 9 mon so she could use that instead, no Terastallizing required (and Kleavor would be useful in a kitchen, maybe not so much in a bakery but still gotta cut up dough and other ingrediants).
Also his catchphrase is "Vaulting Veluza!"
That's an English translation thing. In the Japanese version, well, Bulbapedia explains it better:
Bulbapedia said:In the Japanese version of Pokémon Scarlet and Violet, Kofu says 「ウオーッ!」 whenever he is surprised. While this interjection can be transliterated directly as "Woah!", it also contains a pun on 魚 uo (fish).
