Dudley and Kitty are racing for the last chocolate donut in the T.U.F.F. Headquarters snack room. When Kitty gets to the elevator Dudley sends the elevator down to non-reserved visitor parking, making Dudley the winner. Just as Dudley is about to savor his victory, he gets distracted by Keswick's new invention, a time travel watch. Dudley wants to use the watch to travel back to second grade but Keswick stops him because of the risk of tampering the past that can drastically alter the present. Keswick is about to put the watch away in his vault of dangerous inventions then a waffle iron that only shoots acid attacks Keswick causing him to drop the watch. When Dudley picks it up, Kitty catches up with Dudley and takes his donut. Chief enters in with an article of T.U.F.F.'s latest capture of Snaptrap only to complain about how he blinked in the photo then slips the news article into Dudley's back pocket.
Dudley decides to use the time travel watch to win back the chocolate donut. But when Dudley gets back to the present, he is sent to an alternate dimension where Snaptrap is king. While Dudley is in a slow-motion moment Snaptrap's guards, the "Snapbots", confiscates Dudley's watch for not wearing pants. Its up to Dudley to retrieve the watch and change the present back to its original state. Dudley tries a full frontal assault but it doesn't work so Dudley then distracts one the Snapbots and pummels it and takes its armor posing as one of them. The plan works, and Dudley gets into Snaptrap's castle. Dudley finds the Chief as Snaptrap's butler. Dudley tries to explain to him what happened and that the Chief is the leader of T.U.F.F. However, the Chief doesn't believe him and calls security on him thinking Dudley is crazy. Dudley finds Keswick as Snaptrap's chef then tries to explain to Keswick about what happened and that in Dudley's dimension Keswick is the inventor of T.U.F.F. Keswick doesn't believe him, either, and calls security on him. Finally, Dudley finds Kitty as Snaptrap's secretary then tries to explain to her that she is Dudley's partner and top secret agent of T.U.F.F., but she doesn't believe him and flips him through a wall where the Snapbots find and capture him.
The newspaper article that was in Dudley's back pocket falls out, and Kitty, Keswick, and the Chief pick it up and now believe Dudley's story. Dudley is about to be fed to Snaptrap's sharks when Kitty, Keswick, and the Chief come in and sabotage Snaptrap's bots with the talents they never thought they had. Dudley finds the time travel watch, then asks the trio why they believed him. Kitty tells Dudley about the article and thanks him for helping the group realize what they were really meant to do with their lives. Dudley leaves the scene saying he has to go to the bathroom and changes the present back to its original condition. Dudley, in relief, gives Keswick the watch back then Dudley hears the ice cream truck outside but misses it. Then Dudley uses the watch again to get some ice cream. When Dudley is sent back to the present, he is wearing pants. Dudley, baffled, yells, "HOW DO YOU GET THESE THINGS OFF?!?!?!?!?"
