"Slow down, Thomas! You're spilling my bubble liquid!"
— Mr. Bubbles

Slippy Sodor is the fifth episode of the thirteenth season.


Thomas has a cracked funnel and goes to the Sodor Steamworks for a replacement. The first funnel is too tiny, and the second is too big and tall; so Kevin collects the only spare funnel left, which looks very funny and makes Thomas feel embarrassed. Thomas is then sent to the docks to collect Mr. Bubbles' special bubble liquid for his show. Along the way, all the engines he passes laugh at him. He puffs away quickly, spilling bubble liquid on the nearby road. This causes Sir Topham Hatt and Mr. Bubbles to slip and crash three times. By the time Thomas reaches Knapford, all of the liquid is gone. Thomas rushes away to collect some more. This time, he goes slowly, doesn't mind the teasing and makes it to Knapford safely. The show is a great success, and all the children realise that Thomas' funny funnel looks just like Mr. Bubbles' hat. Thomas later shunts all the engines who laughed at him into a ditch filled with boiler sludge and garbage.







  • This episode screened before the first UK broadcast of the thirteenth season in select US theatres.
  • When Thomas glares at Henry for laughing at his funnel, watch his eyes. They slide from looking forward to looking at Henry, similar to how the model eyes moved.
  • According to The Little Blue Book, Thomas was going to blow a big bubble through his funnel. This idea was carried over for the 4-D attraction, Bubbling Boilers.
  • According to descriptions for the Wooden Railway merchandising for the Splish, Splash, Splosh! DVD, Percy was meant to play a role in the episode, getting splashed at one point by the bubble liquid. This was carried out to merchandising descriptions for the "Slippy Sodor" Gift Pack, as well as the "Percy and the Engine Wash Car" pack "inspired by the episode".


  • In one scene, Gordon's brake coach is at the front of his train, then it is at the back.
  • In some shots, the inside of Mr. Bubbles' mouth is blue.
  • When both Sir Topham Hatt and Mr. Bubbles are messy, the hay is static.
  • In the Latin American version, the narrator said that Thomas stopped at a red signal, when actually he stops at a crossing.
