Buttercream Sundae is a Netherland Dwarf rabbit who has appeared in Topped With Buttercream, among other episodes in which Sweet Delights is present. Full of energy and pep, she's a good dancer but seems to be just a little bit crazy from loads of sugar. Since "Topped with Buttercream", she has become a recurring character in the series. She shows up in the series every now and then.
She is owned by Youngmee Song's Aunt Christie and she is voiced by Cathy Weseluck.
