Isabelle AKA "Puppy Bitch" is a character in the Animal Crossing series. She makes her debut appearance in "PUPPY B#TCH IS A FLIRT YALL! [MARIO KART 8]".
Her main rival is Cat Peach, and she really hates Isabelle because she thinks that she's the only animal in Mario Kart 8. Isabelle also has a couple of guys flirting with her, like Yoshi and Luigi.
Dashie has wondered how old Isabelle is, when she could be in her early 20s.
