Meltman loses his memory after a life-size phone lands on him during a mission to steal a secret formula from The Mayor’s office. The Action League—with help from Bill the Lab Guy—must try their best to bring him back to his previous state.

There’s a new superheroine in town, and her name is Lightning Lady! She wastes no time in getting herself inducted into the Action League and garnering much (male) attention, leaving Thundergirl jealous. Is everything about Lightning Lady crystal clear, or is there more to this mysterious "woman" than once thought?

Loud clog-dancing by Meltman (in midst of a celebration to honor the Action League) goes wrong when it wakes up Spotzilla, a Mesozoic creature that runs rampant upon awakening. After it eats up Stinky Diver during a televised interview, the League realize that they must act fast to rescue one of their own.

The Mayor’s son gets stuck in a kitchen sink during an exploration, and it’s up to the Action League to save him. However, the League's ineptitude at such tasks proves to be an obstacle, with Thundergirl and Stinky Diver spending much of the episode stuck to an active ceiling fan. Can they rescue the victim before time runs out?

A mysterious liquid is squirted onto Thundergirl by The Mayor in a sabotage attempt, resulting in her losing the ability to fly. Once the Action League find out that he has two children kidnapped in a birdhouse, only the power of flight can save them, so the League gets to work—using balloons and a slingshot, among other devices, to try to get Thundergirl airborne.

The Mayor kidnaps The Flesh and unleashes his newest weapon, RoboFlesh: a robot designed to look exactly like his namesake, except for bolts sticking out of his entire body. RoboFlesh goes into attack mode on the Action League, who are having a parade, until the actual Flesh comes to the rescue. The only downside is that the League can’t differentiate between the two!

After a failed attempt at saving a victim from a flushing toilet, Stinky Diver goes on a downward spiral. The Action League must work together to bring back to courage he once had. In the end, Stinky will have to overcome his fear of long-distance diving, but only in order to retrieve his wallet, which is in the hands of a drowning Meltman.

Upon the death of Helena XXII, Queen of the Pigeons, the Action League are given the task of keeping the four eggs she's left behind safe until they hatch. After accidentally breaking one of them, The Chief makes the League responsible for a 24-hour surveillance of the remaining batch. Will there be any offspring left by the end of the episode?

The episode starts off where the first half stopped, with The Flesh swinging a leash and attaching it to the collar of a running Spotzilla, unable to stop him after a short, rough-and-tumble trip. Will Stinky Diver remain within the realms of Spotzilla's massive stomach for good, or can the Action League come through before digestion occurs?

The Action League are given the task of protecting a young child from The Mayor for an upcoming testimonial. However, things take an ugly turn when the child turns out to be a complete nuisance, physically injuring and disposing of the League in a number of ways. Once he has gotten them out of his way, The Mayor goes on the offensive with a surprise.

A rocket that is being prepared for takeoff contains The Chief's beloved dog, Justice, within its realms, a plan executed by none other than The Mayor (as revenge against Justice for peeing in his hot tub). Can Thundergirl's flying ability and Meltman—who has been thrown onto the rocket via The Flesh's strength—be able to save the plastic pooch?

The Mayor is driving through town, littering just about everywhere, and it's up to the Action League to chase him down and stop him from continuing his heinous ways! Can the League (in their Action Mobile) overcome The Mayor (in his much, much bigger automobile) before the entire town gets covered in trash?

The Mayor interrupts The Chief, in the middle of a date on the mountains, by sucking him up inside a gigantic vacuum cleaner. Not long afterwards, the rest of the Action League get trapped inside the structure, as well, and the only person who can save them is Meltman—who was made fun of by the League only seconds before!
