She became friends with Tommy in the episode Opposites Attract. When she first introduced herself to Tommy, she said her real name's Samantha, but that everyone calls her "Sam" for short. Sam's very adventurous and much less sensible than Tommy is. She is also a bit of a rule breaker and got many booboos as a result of breaking the rules. Although Sam means well she is a bit of a daredevil. She also likes mud, swings and rocks. The booboo on her right shoulder was from falling in the dark, the one on her left arm comes from pulling on the lampshade (which was against the rules), and the one on her chin was from climbing on the table (also against the rules).
