You were an engine working on Sodor, you were finished carrying passenger coaches and shunting freight cars from Thomas was showing you, he knew that you were good at it.

One day you went to the washdown and then you saw Emily the Emerald Engine there, she was having a washdown, she was covered in soap suds, feeling the soap within her engine boiler and tender and her wheels were getting lathered with the soap.

She was looking at you, "hmm, I bet you've seen engines going to the wash down before, you see how we're always getting clean to work on The Fat Controller's railway, and yes engines do take baths by going to the wash down take it from me!"
