The Stinky & Dirty Show S01E07 - Lost! / Squeak

Lost!
When Stinky and Dirty get lost in a thick fog, they come up with new ways to "see" and use smell and hearing to successfully find their way home.

Squeak
When Dirty develops a squeak that keeps him and his fellow trucks awake, he and Stinky go in search of a solution and discover that while some sounds keep you awake, others are good for helping you sleep.
