The Great Brain Drain / The Great Double Double Cross - S1.E5

The Great Brain Drain: Dr. Strangemind has created a potion that makes the drinker start acting like a child. Baron plans on using this potion on all the world leaders in his quest for world domination. Lancelink goes in to intercept the potion, but in an act of desperation winds up drinking it. With Link now imprisoned by CHUMP, Mata has to come rescue him.

The Great Double Double Cross: Mata and Lance both show up at APE headquarters at 3AM. Unbeknownst to everyone else, it is really Baron and Dargon Lady posing as the two agents. The next day, the whole office has been ransacked and a list of APE's top agents was stolen. Darwin gives the two real agents 24 hours to return the list to APE headquarters to clear their name.
