The Return of Smudger!

Smudger returns because he's an engine again, but he's still a little naughty.

Smudger: Heh, heh, heh, he, heh, heh! You'll be laughing on the other side of your boiller soon, silly engines! Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha! Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha! HA, HA, HA, HA, HA, HA, HA, HA, HA, HA, HA, HA, HA, HA, HA! Yes!
