When Gumball discovers Mr Robinson in the Watterson shed,
he feels sorry for him and brings him into their attic.
Dad hears noises in the attic and is convinced that there is a ghost in the house.
Gumball and Darwin notice that something is wrong with Mr. Robinson,
and set about trying to “fix” him. Eventually Mr. Robinson reveals that his wife threw him out because he had lost his anger.
Needless to say, Gumball and Darwin manage to reignite his anger,
assisted by Dad (who attacks Mr Robinson believing him to be a ghost) and the Robinsons’ marriage is saved.
