The author of Choo-Choo Charles built a whole game around this meme: the protagonist ends up on an island whose inhabitants are being attacked by a toothy hybrid of a spider and a steam locomotive named Charles. The player has his own locomotive to move around the island, which can be armed and customized. After completing the instructions of the local natives and receiving components for an upgrade from them, it becomes possible to call a terrible mutant to the final battle.
For the most fearless, we have created a collection of Choo-Choo coloring pages. Download for free!
