Larryboy is on a ferris wheel at the local carnival when the cotton candy machine malfunctions. Following its violent explosion, Archie discovers a bottled substance known as Ultra Sucrose Enhancement Catalyzer, which Olaf suspects was used for "chemical sabotage" of the machine. Larryboy runs into the Alchemist and is about to smell his flower; however, Olaf warns against it just in time and Larryboy supposedly sniffs no trace of the powder from the flower. However, after the Alchemist is thrown in Olaf's van and driven off, Larryboy begins to feel superior to the entire town and puts down the citizens, causing them to be shrunk, captured and taken to the Alchemist's lab. Larryboy soon realizes what he's done and arrives at the lab, only to be confronted by a much deadlier and more dangerous version of himself, the Alter Ego. After enduring its power, Larryboy verbally remembers he needs help from Archie and his friends, which causes the Alter Ego to shrink and eventually disappear, returning everyone to normal size. In retaliation, the Alchemist takes Bob hostage. After dropping him at Herbert and Wally's firing of jelly donut juice at him, he inadvertently releases the powder on his mother (Mother Pearl), who flings it back at him and shrinks him, after which they both are apprehended and arrested for their villainous acts.
