The title Hamusuta is the Japanese rendering of hamster, which explains its cute, small-animal association, even though no specific show, character, or original recording is identified for this clip. Short clips with animal-inspired names circulate widely on soundboards and in short-form video, where listeners save the ones that are instantly recognisable and easy to reuse. Hamusuta fits that pattern: it is brief, light, and memorable, so creators keep returning to it for gentle comedy and wholesome pet-style moments rather than for a reference that needs explaining.
