Pichu is the baby pre evolution of Pikachu, introduced in Pokemon Gold and Silver in 1999, and later became a familiar face in the Pokemon anime and games. Its small size and squeaky voice made it a natural fit for cute edits online, and peek a boo clips pair that image with the classic hide and reveal game. Short versions circulate on soundboards for quick reactions, especially in family friendly fan videos, pet posts and streams where a gentle cute cue works better than a startling effect for viewers of all ages.
