The Thin Controller, Rheneas and others in “Rheneas and the Dinosaur”

Rheneas and Skarloey, you are NOT careful engines! I will have to choose 2 other engines to collect the dinosaur.

But I can be careful. Let me try again. Please?

Very well, but this is your last chance.

Thank you, sir.

I'm sorry I biffed the trucks, but I'm sure we could take the dinosaur together.

No! I'll show Mr. Percival I can do it on my own!
