The episode begins with F.L.O.P.P. who are released from prison. Meerkat, introduces a new agent named Bluffalo and he says that he has a "stolen car" (he really bought it), and says that the only way to stop T.U.F.F. is with lies, convenient lies.
Meanwhile at T.U.F.F., Keswick performs a magic show which he takes out a coin from Dudley's ear. Dudley thinks that his head is full of coins, and starts getting coins from his head (that is a gag all the episode), Kitty says that Keswick is amazing. Keswick says that is not his only ability, he also knows the names of Petropolis streets in alphabetical order. Meanwhile F.L.O.P.P. calls T.U.F.F. and says that they're gonna to shrink all the city. Dudley and Kitty go to stop them, but they land onto a "Shrink Petropolis" (made with ice cream sticks). Kitty knew that it was only a trick, and says to Dudley that he must to be alerted.
Back at T.U.F.F., Dudley uses an aspirator to get all the coins from his head but accidentally sucks his brain. Then, F.L.O.P.P. calls T.U.F.F. again saying that they're released an "Evil Dragon" in Chinatown. Kitty says that they're not gonna to fall for that trick. Dudley is disguised like a knight and goes to Chinatown via bus. All the passengers are scared and Dudley IS kicked out by the bus's chauffeurs saying that he can't get a lance, but the "old woman" can scream and bleed. Dudley comes to the Chinatown Parade and attacks the "Evil Dragon" and "saves the "eatened people" and then appears D.O.O.M. with Chinese costumes. Snaptrap says that Dudley is ruining the attractions again, and Larry adds that he attack he with a lance in the bus. Snaptrap says that actually was he, that did that. Kitty arrives and gets Dudley out of Chinatown stating to Dudley that F.L.O.P.P. tricked them again (in this scene Kitty mentions her mom and sister, saying also that her family is weird).
At T.U.F.F. HQ, The Chief says that he has spoken to the Mayor of Chinatown who has agreed not to press charges in exchange that Dudley doesn't visit Chinatown again, pronounces "China," and/or eats on China. Dudley is still trying to get the coins out of his head. Meanwhile at F.L.O.P.P. HQ, Meerkat says that with lies they haven't progressed much and decides to use the Box of Doom (A black cube with the sides red, with a red skull in it, and has a black hole inside of it) and then repeats the gag from Top Dog: Where Snaptrap is in the Mini Golf lost and found storage, in this case he takes a vase with pens in it. At back in T.U.F.F., while Dudley continues trying to get coins, F.L.O.P.P. calls again says that they're gonna to destroy the world. When they noticed that Dudley is the only one there, Dudley states that everyone else went out for Dimsum since "there still allowed to to go to Chinatown."
Dudley arrives at the Mini-Golf (in bus) and is kicked out by the bus's chauffeur. F.L.O.P.P. activates the machine but unfortunately, the black hole appears and starts to suck all the world. Meerkat asks if that supposed to start happening, and Wanna Bee says to not touch the button if you want to live, and the four get sucked by the Box of Doom. Kitty arrives and says that Dudley must turn off the machine, and then Dudley comes from a vending machine with chewing gum. He starts to chew it and with it locks the Box of Doom, saving the day and he says that F.L.O.P.P. isn't arrested. But it was only a lie and the bad guys are arrested.
Meanwhile at T.U.F.F. Keswick tells Dudley that his head isn't full of coins. Dudley says that he already knew it because he takes all the coins from his head (appears with a cart full of coins), and goes to buy a ping-pong table, pay the bus's chauffeur and buy flowers for the "old woman" that he hurt accidentally. The Chief says that he, Kitty and Keswick start to take out coins from their heads. And then appears a black screen and Snaptrap asks if someone wants to buy a pen, and then the episode ends.
