Buttercup is an unusual rattlesnake. She doesn't like mischief, is afraid of mice, and has a sweet tooth. Buttercup goes on an adventure to crash a little girl's birthday party where she devours the cake because of her love of delicacies. After thinking she will cause a fury and must leave the party in a hurry, the birthday girl tells her mother that she was the one to actually invite Buttercup to the party.
