A.T.O.M.

Zoo Story (2x20)

Air date: Jan 20, 2007

A peaceful day at the city zoo for Axel, King, and Shark turns into another fight with Lee and the Mu-Team when the latter are there to use the zoo's newly-acquired Hybridon (the mutant amalgam of animals responsible for the previous closing of Blue Pines National Park) for nefarious purposes.
