A bug yodels up Mount Everest looking for a golden butt, and somehow that's exactly as charming and unhinged as it sounds. The music carries you the whole way, this isn't a novelty video coasting on a joke, it's a genuinely well-crafted song that makes climbing a mountain in pursuit of literal ass treasure feel like the most natural thing in the world. Five years later and UrumaDelvi still understands that the best children's content doesn't talk down, it just commits completely to the bit and trusts the absurdity to do the work.

Oshiri no Yama wa Everest is a single music video made for NHK's Minna no Uta program. It is the second video starring UrumaDelvi's butt-biting bug, and it arrived five years after the original song first aired. Oshiri Kajiri Mushi XVIII sets out to climb Mount Everest in search of a fabled golden butt, and he yodels the whole way up to the peak.
