Many-Mouths' memory

S4 E11: Many Mouths has taken a hit to the head and has lost his memory. He doesn’t even know his own name! Double-Tooth is standing in as chief beaver, but a storm is brewing and the dam must be reinforced and, unlike Many-Mouths, he has no idea how to lead operations. Yakari tries to help Many-Mouths get his memory back by feeding him his favorite food: blackberries. But after stuffing his face, Many-Mouths falls asleep. However, as he is sleeping, he talks in a fearful voice of “Bison Pass”. They head out there along with Mic-Mac and Little-Thunder, but the bison start heading right towards them. Reliving the scene during which he lost his memory, Many-Mouths then remembers everything.
