Meanwhile, Flambo attempts to thwart Dr. Whiskers' evil plan to reverse the rotation of the Earth.

Plot
The episode begins with Zippy waking up and realizing that it is April Fool's Day. Zack sees him and wonders what Zippy is so pleased about, until he looks at the calendar, and realizes that it is April Fool's Day, which he says is one of Zippy's favorite holidays. Fearing the worst has to come, Zack calls Mr. Red saying he caught something terrible and that he would not be able to make it to work. Mr. Red says that there is an art collector in his office who wants to buy Zack's art and name him artist of the month. So, Zack immediately rushes to the Burger Shack, only to find that it was a silly prank by Zippy and Wet Willy. Zack attempts to resign from his job, but Zippy persuades him to stay, promising not to pull any further pranks on him. Mr. Red warns Zippy and Willy to watch out for What's-It's-Face (especially on April Fool's Day). He explains that What's-It's-Face is his arch-rival, and has been pulling silly crimes for years.

Meanwhile at Zippy's house, Flambo is walking nearby his dog house. He stops and checks to make sure no one can see him. He goes into his dog house and turns on his TV. Bubbles the fish informs him that Dr. Whiskers has bought "80% of the country’s tin foil." Flambo must find out why and stop him. Before Flambo leaves, Bubbles reminds him to maintain his cover as a "normal domestic pet." Giving the fish a quick salute, he rushes off.

In the city, barge captained by a robotic clown and carrying green garbage that emits green gas floats over the river. An armored truck driver smells the gas and starts laughing and driving erratically. More people smell the gas and start laughing as well. The victims seem to have lost all sense as the truck driver drives his truck right into the river.

At school, Zippy continues to prank his classmates while not pranking Zack. The students do not take offense to Zippy's pranks as they are harmless and playful in nature and they even laugh with Zippy. The fun wouldn't last when he hears a report on the radio about people who are having nearly fatal accidents on the bridge due to them acting like complete fools. Zippy deduces right away that it's the work of What's-It's-Face. Meanwhile, What's-It's-Face's henchmen, Von Papperorth and Freddy Bear dive and steal the contents of toxic waste while What's-It's-Face fixes himself up to go out towards the financial district. Once the ship has docked What's-It's-Face and his men go out with shopping carts and gas masks (or in What’s-It's-Face's case, a fishbowl) and start stealing from the people and the stores in the area. The people are so busy laughing and dancing around that they do nothing to stop it.

Nearby, Flambo bursts in through a doggy door at Dr. Whiskers' appartment. Dr. Whiskers greets him with: "Ah, Flambo The Dog! What an unexpected surprise. And by unexpected, I mean completely expected!" After trapping Flambo, he informs him of his plan to move the Eastern Seaboard (now covered in tin foil) to the West by using a "Magnetism Magnifier," which will reverse the rotation of the Earth. While Whiskers is talking, Flambo tries getting free of the robot arms holding him, but then notices a screw on the ground at his feet. Looking around him, he formulates a plan...

While What's-It's-Face and his men go on their shopping spree, Zippy and Wet Willy does an analysis of the gas and learns that prolonged exposure will result in permanent insanity. Zippy calls up Ceela and Jenny for help but Ceela blows them off. At first, Willy thinks it's just a joke but he hears crashing and runs upstairs to find that Ceela and Jenny has been exposed to the gas, and is destroying most of the library in his lunacy. Quickly donning a gas mask, Zippy and Willy realize that he must stop the gas before it's too late.
