After being released from prison, the The Chameleon decides to take revenge on T.U.F.F. by infiltrating headquarters and pressing the self-destruct button. Back at T.U.F.F., The Chief arrives to see the place in shambles, caused by the loss of his secretary (according to Keswick, they literally lost her after she took a 10-minute break; she's somewhere under the ocean of paper). Seeing this as his opportunity, The Chameleon disguises himself as Fifi Oui Oui, and uses a bad French accent (which he thinks is authentic). With this disguise, he has no trouble fooling the agents, despite the brief relapses into his insanity, and the fact that he still uses his normal voice. However, Dudley has fallen in love with Fifi, and with Kitty's help, tries to impress her…and throws up on her, then gives her toilet water, then spits on her after she does it to him, then causes her dress to catch on fire, and beat her with a broom to try and put it out. Desperate to save himself from winding up in a hospital, The Chameleon tricks Dudley into showing him where the T.U.F.F. self-destruct button is…which is in the snack room, on the vending machine. Distracting Dudley with a tennis ball, The Chameleon prepares to complete his plan, but is taken away by Kitty, who tells him about Dudley's crush (which "doesn't" creep him out), and tell him to give Dudley a chance. Now alone, The Chameleon finally pushes the self-destruct button, but only after getting hit by a boxing glove, being crushed by an anvil, and getting attacked by a gorilla. With the self-destruct button activated, The Chameleon heads to the supply closet to steal some pens for his home office, but runs into Dudley, who asks the love of his life to a date…which is in one of T.U.F.F.'s elevators. Oblivious of what is about to happen, Dudley proposes to Fifi, which she hastily accepts, but then Dudley spills his drink on Fifi, causing her to reveal her true identity as The Chameleon, and Keswick started to faint. His secret is blown, The Chameleon reveals what he has done, and while Dudley and Kitty are distracted, disguises himself as salad dressing, but becomes trapped in the elevator, as only authorized agents can operate them, and the following explosion of T.U.F.F. HQ sends The Chameleon back into his cell. Once the place is repaired, Dudley tries to celebrate, but accidentally presses the gorilla button on the vending machine. However, The Chief is excited because everyone gets to evacuate again!
