Interrupted from reveling at the full moon by his growling stomach, Momotarō decides to seek some sunflower seeds and becomes infatuated with a female squirrel prior to transporting his payload. Unfortunately, Momotarō loses his balance and unwisely tries to save the seeds—the penalty of which is induction into the slipstream of a passing truck and being electrocuted.
