When Dad forgets Mom’s birthday,
he sends Gumball and Darwin to the local gas station to buy a present.
Unfortunately a stick-up is underway,
and the robber manages to con Gumball and Darwin into assisting him.
He tells them that he is collecting for a baldness charity.
When Mom and Dad come to the gas station to check up on them, they are taken hostage.
Gumball and Darwin realise that they have been duped and are determined to save the day. They don’t.
But Mom does. Who then gets arrested. On her birthday!
