Big Larry is one of the 7 monsters in the lab and also one of the first four ones that existed. Big Larry cannot speak, but he can jumpscare and kill the baboons. It is unknown if it attacks humans or just the monkeys in the lab. Big Larry is a baboon similar to the player (with no legs and long arms which he uses to walk) has grey fur and a fleshy stomach and face with empty eye sockets and a mouth in an “O” shape with razor teeth. When he’s near, distorted and slowed down ragtime music plays.
