Episode Title:
The More You Moe, the Moe You Know.
Episode Description:
A MO claiming to be Moe visits for BMO's birthday, bringing a special mission for the robot: return to the MO factory to grow up. BMO is nervous, worrying that the process of growing up may affect the way others see it. At the MO factory, BMO, after nearly falling into a trash compactor, learns that the real Moe went offline yesterday, and that the MO at the tree fort is actually AMO, the first MO ever created. AMO was built to receive love, and has become desperate for affection at any cost. Realizing that AMO has attempted to take its place and receive the love of Finn and Jake, BMO rushes back to the tree house, and in the resultant scuffle, AMO is accidentally hurled off a cliff.
