Ep 2. Trench Trouble / Glitch Day Galore

In "Trench Trouble," when a new truck named Trencher shows up to help on a big job, Dug feels like this role on the team is at risk, and lets his insecurities get the better of him. But when a surprise puts the whole job at risk, there's only one truck who can save the day - Dug! And that's when he realizes that everyone on a team has something to contribute, even if it's not obvious at first. In "Glitch Day Galore," when Sparky's bucket starts giving her trouble, Tork sends her and Blinker to the mechanics' garage for a check-up. Blinker is overjoyed, but for Sparky - who hasn't had a proper check-up in a long, long time - the visit is full of anxiety and learning about all the things that make Terrific Trucks go.
