Amumu has been part of League of Legends since its early years as the Sad Mummy, a small undead champion known for his lonely, gloomy personality. This short entry, however, is not presented as an official game line; it reads as a user-uploaded reaction clip, tagged with Brazilian Portuguese slang and a creator-style handle. That informal, community-made character is part of its appeal, letting players reuse a familiar champion name as an inside joke in streams, edits, and chats rather than as a quote from the game itself.
