Wooper is a Water and Ground type Pokémon from the second generation of the Pokémon games, known for its round blue body, cheerful expression and distinctive vocalisation. Its repeated upa sound became a familiar part of the character's identity in games and animation, where Pokémon often speak variations of their own names. Online, the clip has been lifted from that context and reused as a meme sound, shared on soundboards and dropped into short edits for its cute, instantly recognisable tone. Its staying power comes from that simplicity: a two second burst of Pokémon nostalgia that needs no explanation.
