Happy Time Plan is a multiplayer puzzle game adapted from Bobby's game time. Among seven players, one player will choose to be a monster, and six players will act as survivors to obtain toys through puzzle solving. They will put them in a toy machine, synthesize huge toys, and flee on the train. The monster's task is to knock down all players to win! All players can choose skins, palms, clothes, and so on Monsters can also have skins. The game has added new monsters, which are more frightening than boxes. They have two special skills, which can jump very high and extend their hands, similar to Mommy's. Monsters can choose skills, such as destroying palm shots, destroying all machines, prohibiting all players from hiding in cabinets, and so on
