Twas the Fight Before Christmas:
The Chameleon wants to give Maximus the best Christmas present ever -- the destruction of Atomic Betty. He disguises himself as Galactic Guardian trainer Commandant McSlim and lures Betty and her crew over to Galactic Guardian Academy for "retraining" over Christmas holidays... all under the watchful eyes of Maximus and a jealous Minimus. Meanwhile on Earth, Betty dresses as Santa to help spread holiday cheer to some pre-school kids.
Toy Hystoryia: Evil baby Infantor becomes greedy at Christmas time and demands all the toys in the galaxy. He kidnaps Santa and takes over control of his factory at the North Pole Star, reprogramming the toys to his specifications. Betty and her crew have to rescue Santa and save Christmas for the entire galaxy. Meanwhile on Earth, Betty accompanies her parents to the mall, where she must help her Dad get a gift for her Mom before the stores close.
