You were shunting some flatbeds, so the lumberjacks can load them up with logs. You were a bit bored waiting, so you looked around, trying to find anything you don`t know. Then, you saw a box shaped engine, who was sleeping in the shed. You whistled to get his attention.

AH! OH GOODNESS!

The box engine yelled in horror, as he woke up instantly, breathing heavily.

Hoh..

Huh..

What was that..?
