Chuggington (2008)

Episode Overview

On a chilly winter day, Wilson and Koko are tasked with spreading sand on the mountain tracks. They decide to take a shortcut through an ice cave. Koko diligently focuses on the task at hand, but Wilson gets distracted by the cave’s wonders. Unbeknownst to him, an icicle has dropped into his sand wagon, soaking the sand and making it ineffective. Realizing he's in a bind, Wilson cleverly uses his engine’s heat to dry the sand and manages to return to the depot—after completing his job, of course!
