The Fat Controller and Edward in “Trouble in the Shed”

Bless me! What a noise!

They all hiss me, Sir. They say tender engines don't shunt, and last night, they said I have black wheels. I haven't, have I, Sir?

No, Edward. You have nice, blue ones, and I'm proud of you. Tender engines do shunt. But all the same, we do need another tank engine here.
