Torahamu-kun, called Stan in English-language media, is a male hamster and the fraternal twin brother of Sandy, owned by human Noel. He stands 7.5 cm tall and shares a June 6th birthday and Gemini zodiac sign with Sandy. Stan has a cream-colored underbelly, a peach-tone tail less fluffy than Sandy's, and no tail ribbon. He frequently carries maracas or uses a skateboard. Stan possesses a highly flirtatious personality, constantly attempting to woo female hamsters like Bijou, Pashmina, and Flora. This behavior irritates male Ham-Hams such as Boss, Howdy, and Dexter, who view him as competition. His sister Sandy actively intervenes when he flirts with her friends, often dragging him away by his tail using her ribbon. Despite this friction, Stan cares deeply for Sandy; their bond is reflected in their childhood song "Twirling Whirling" ("Kuru Kuru" in Japanese). Stan's primary romantic interest is Flora, a nurse hamster. In one episode, he fakes illness for her attention, resulting in disaster. After realizing his mistake, he cleans her entire clinic without permission to make amends. Flora responds positively, giving him a Valentine's Day gift suggesting mutual affection. Stan also briefly dates Lapis in a seemingly more platonic, situational instance. As a character, Stan seeks attention and enjoys being the center of it, sometimes causing trouble. He is athletic, skilled in skateboarding and snowboarding, though less proficient than Sandy. His backstory reveals he was separated from Sandy as a baby when Noel adopted him; they later reunite through the Ham-Hams' efforts. Stan's development consistently emphasizes his flirtatiousness, relationship with Sandy, and occasional growth in understanding social boundaries.
