Dragon Ball - episode 40 - 25 Nov, 1986

Goku and Eighter land on 5th floor. General White releases a monster to destroy the both of them. Meanwhile Snow has found some sweet furry rodents. Eighter cowers at the other side of the room while Goku fights the monster Buyon. Goku can't even hurt Buyon. Buyon eats Goku, but he struggles out. Even a Kamehameha Wave doesn't affect Buyon. Goku saves Eighter from being eaten. Recalling an earlier exchange with Snow, Goku punches a hole in the wall letting in cold air and freezing Buyon solid. Goku smashes Buyon and ascends with Eighter back to the command room. (Source: Wikipedia)
