| Please note the following:
Salty or referenced as The Ugly Red One by Bowser Junior is a wooden toy train from Thomas & Friends. He is part of a running gag in which multiple people are playing with Bowser Junior's trains and, though they insist on playing with Thomas, Bowser Junior makes them play with Salty instead. This irritates many characters, especially Black Yoshi. He was burned in Bowser's House Fire! along with almost all the things in there, except for Thomas and the picture from Bowser Junior Goes To The Fair!. After the house fire, he has not been seen ever since possibly meaning he died in the fire.
- Despite his real name being on his side and undercarriage, Junior doesn’t know his name, unlike how he knew Percy’s name in Bowser Junior Orders a Pizza.
- In real life, Salty is based off a British Rail Class 07 dock switcher (shunter) locomotive.
