An accidental zap from the Fresherizer ray turns Skipper into a baby. The gun tumbles into the sewer, and Kowalski, Rico, and Private leave baby Skipper in Julien's care. They are captured by the Rat King, and baby Skipper must escape in order to help them.The zoo animals are in a panic when word reaches them that the boa constrictor has escaped from the Zoo and is heading to them. They do their best to set up a perimeter, but the snake breaks through and captures them all except Julien.
