Book 1: Frick.

Plot
One day, Big Doot was puffing along the tracks. He was daydreaming about his idol, Thomas the Tank Engine. Suddenly, BANG! Big Doot bumped into another engine. He was too caught up in his dream! He slowly backed up and he realized somehow... He had bumped into Thomas! Big Doot wanted to apologize, but he couldn't get any proper words out of his mouth... He ended up saying "Hee wa hbeek hhhhhhhhhhh!" Thomas was a bit weirded out, and continued with what he was doing. Poor Big Doot made a fool of himself.
