Mr. Cat tells the others about a serial killer called Bob the Kebaber. Since Kaeloo doesn't believe him, he takes them back in time to 18th century London, where Bob allegedly lived.
"Let's Play Time Travel" contains the following tropes:
- Bloodless Carnage: Stumpy gets skewered through the abdomen by a giant corkscrew, but doesn't bleed.
- By the Lights of Their Eyes: Since it's a foggy night in London, the main four are stuck in pitch dark upon arriving and the only thing visible is their eyes.
- Crazy Jealous Guy: Mr. Cat comes across the other three playing Sleeping Beauty, with Kaeloo as Sleeping Beauty and Stumpy as the prince. Before Stumpy can get to the princess, Mr. Cat threatens him with a bazooka and orders him to stay away from Kaeloo, so he quits the game.
- Newhart Phone Call: When Mr. Cat calls the time machine company so that he can order a time machine, the person on the other end of the line can only be heard as sped-up gibberish.
- Time Travel Episode: Mr. Cat takes Kaeloo, Stumpy and Quack Quack back to the 18th century to prove the existence of a serial killer.
- Tradesnark™: "Time Machine Express™", a company that sells time machines. Averted in the English dub, where it's called "Time Machine Instant Delivery".
