The Root Pack– Moe Tato probably is the best singer of them honestly; he mostly keeps it as a secret because he thinks people will see him as weak. Weepy’s pretty good too, and he tries to get Moe more comfortable singing. Psycarrot? He’s terrible. Hey, can’t be good at everything.
Goopy Le Grande– He’s actually pretty good at it; “Another bullet point on my already impressive resume!” He uses it to brag most of the time, but sometimes he’ll use it for a good cause.
Ribby and Croaks– Together, they form a really good harmony; separate, they’re alright. Nothing spectacular, but nothing to sneeze at.
Hilda Berg– She’s really secretive about her singing (and probably about a lot of things in general), but if she trusts you enough, she would sing for you. And she’s a gorgeous singer. A lot of the Isle 1 folks think she’s the best singer on that particular island. Well, except one.
Cagney Carnation– You wouldn’t really expect a flower to be so good at singing, but Cagney takes those expectations, throws them out the windows, and chokes them with his vines. He sings a lot; “It’s scientifically proven that flowers grow better with music. How’d you think I got so big?” It’s mostly a lot of Latino songs to get your blood pumping, and the Isle folks love it! One of the few things he and Hilda argue about is who’s the better singer. Well, Cagney does a lot more of the arguing; Hilda just kinda ignores him. She doesn’t care that much.
Bonus: Cagney tries to get the other folks of Isle 1 to say he’s the better singer, but they just avoid him. They know better than to annoy the flower.
