Tim

Tim is Big Head's longtime close friend. He's very smart and has one hand.

Big Head and Tim
Big Head and Tim are out walking when Big Head suddenly gets sniped by Jetpack Guy. Old Guy checks the timeline to see Big Head will be killed, so he goes back in time and texts him to warn him. Big Head does a flip and dodges his bullet. Big Head then floats away with Tim. Tim is holding on to Big Head's head but slips and falls and dies. Old Guy goes back in time and texts Tim to warn him. He climbs on top of Big Head to avoid falling to his doom. In the distance, Jetpack Guy is following them.

A large hand tosses the characters into Heavy's dimension. Old Guy and Jetpack Guy both fly away. Big Head finds a ? block and gets a tanuki leaf. Tim latches on and they soar into the sky. Jetpack Guy sets his gun to rocket mode, but the giant hand intervenes and throws everyone into the Captain Tood dimension.

Everyone goes their separate ways. Jetpack Guy notices Big Head and Tim, so he chains them up and brings them to his hideout. He throws them in jail. In a cell next to them Starfish Face starts a conversation, saying he's been in so long he had to eat his own legs to survive. Suddenly, Old Guy flies in and unlocks both cages. Old Guy says it's good to see his son again, but it isn't revealed which of the three is his son. The giant hand tosses the characters over to a giant Heavy, who brings them to a random dimension. They live there now.
