Danny Phantom (2004)

S1E18 Life Lessons

Danny and Valerie Gray find themselves unexpectedly "parenting" a bag of flour for a week-long school project. Meanwhile, Skulker, the ambitious ghost hunter, decides to challenge Valerie and Danny Phantom to a showdown—where the winner gets to be his next target. When the competition ends in a stalemate, Skulker handcuffs the pair and begins to chase them through the Ghost Zone. To escape, Danny and Valerie must put aside their differences and work together, which could potentially alter their dynamic back in the real world. Or maybe not.
