I find Peanut's "slacker" to be sweet, but also discomforting. Something about her sort of calling you a slacker is a good attempt to be nice but gone wrong, lol.
I also like Fang's "cha-chomp." I think it fits him well.
i don’t remember many catchphrases but zucker’s “bloop” is adorable - simple but cute and matches him well. i also find it interesting that him and bertha have the same catchphrase aha - i had them both on my island at one point so there was a lot of “bloop” to go around
Merry’s Mwee might actually be my favorite or Rudy’s mush. If I had Tom or Moe, theirs might be my favorite since I seriously love cats too much lol...
I used to not like Punchy’s “mrmpht” but now I refuse to let him change it lol. I don’t know if that’s my favorite though.
sulky is iconic and so cute to say. for my other villagers, i've given them catchphrases (that fits them) for YEARS that i started to think it was their original but it wasn't lol. i gave static "zap" but i keep forgetting it was originally "krzzt"
also i love mrmpht & pthhpth, it's so silly that it fits them.
Another one I find pretty funny is Hamphrey's. He says "snort"...
Looking at this little hamster and his bushy eyebrows, acting like a grumpy old man just cracks me up.
Ooh I love a few of them. Apple’s “cheekers” is absolutely adorable.
I also have Aurora and I did like the “b-b-baby” however my bf and I made the decision to change her catchphrase to “b-b-bruh”
I also love that Cousteau says “oui oui” and Chadder says “fromage”
Love the French in the game.
I've always liked Quillson's "ridukulous". I use it fairly often myself now. Hah!
I also think that Shep's "baaa" is pretty funny. Since it's an onomatopoeia, he sounds like a sheep when he says it. (I've come to the conclusion that AC speech (in the US) is just sped up clipped English. If you listen closely enough, you can make out many words. The "baaa" is quite obvious, though.)
