Torahamu-kun, commonly called Stan, is a male hamster and fraternal twin to Sandy. Separated during infancy, he reunited with her years later through the Ham-Ham group’s intervention. Stan’s flirtatious antics frequently target female hamsters like Bijou, Pashmina, and Flora, provoking irritation from rival males and prompting Sandy to rein him in by yanking his tail with her ribbon.

An avid skateboarder and snowboarder, he sports a laid-back, athletic charm, often seen shaking maracas. His cream underbelly, peach-toned tail (less fluffy than Sandy’s and ribbon-free), and energetic posture set him apart from his sister. Though prone to squabbling, their bond endures through a shared childhood melody, "Twirling Whirling" ("Kuru Kuru" in Japanese).

Stan’s infatuation with Flora, a nurse hamster, drives him to feign illnesses in episodes like "Kind Flora" and "Come on, Stan!". After persistent failures, he secretly cleans her clinic, earning her gratitude and a Valentine’s gift. A fleeting reference in "Hamtaro: Ham-Ham Games" hints at a past romantic disappointment with Lazuli. His dynamic with Sandy blends rivalry and loyalty: she chastises his mischief yet fiercely defends him.

In "Lady Lapis!", Stan arranges a platonic outing with Lapis to boost her mood, showcasing a rare selfless streak. While his romantic pursuits often lack depth, his actions occasionally reveal hidden sincerity. His broader history and connections align with established series lore, though his role in "Tottoko Hamutarō: Ham Ham Ham - Jya! Maboroshi no Princess" remains unspecified in available sources.
