Buttercream is a female yellow and brown Netherland Dwarf rabbit with dark green eyes, who is a dancer. A later addition to the group, Buttercream's owner is Youngmee Song's Aunt Christie, who owns the candy shop named Sweet Delights. She is very active and hyper, but also very mischievous. A running gag is that she has a habit of saying overly sweet, hyper, and nonsensical statements (possibly from constant sugar hypes) and whenever she does, one of the pets will say catchphrase "What?" to her. Buttercream calmly responds with another "What?", twirls her ears with a twanging sound, and then relaxes herself before saying "Anywho."
