Construction Site - Season 1

When the younger machines accidentally knock a load of oil drums into the dock they are too scared to own up to their mistake; Diggs and Scooch thing they're saving Bozer some time by digging a pond, but they put it in the wrong place.

When Diggs saves Carl from a nasty accident, the older machines decide it's time he started hanging out with them; After reflecting on his carefree youth, Lug decides that he's not ready for old age and joins Diggs and Scooch for some 'top gear' fun.

Scooch's voice is too quiet to stop Lug from crashing, and Scooch worries that the older truck will never forgive him; Diggs frightens Carrie and Schooch on a junkyard run with tales of a scary monster named "Truckzilla."

Diggs, Carrie and Scooch are tired of the old machines always telling them what to do, and want to prove to Bozer they can work on their own; Bozer tells the machines that it's "out with the old and in with the new," to Carl and Lug's chagrin.

Preoccupied because he misses his birth site, Carl almost drops a pipe on Diggs, leading the others to try and cheer him up; Diggs is jealous when Scooch chooses to work with Carrie instead of him, so Diggs impersonates Carrie to win back his friend.

When there's cement mix to be moved and Carrie's feeling fired up, nothing can stop her -- nothing except a dead battery that is; Carrie chooses to horse around when the machines are clearing out an old dock, and has to be rescued by Carl.

The new machines have a lot of bricks to move, so many in fact that Diggs thinks they could use a little help from Maxine; When Diggs, Carrie and Scooch dig a trench in the wrong place they think they've struck oil and dream of riches.

Diggs is proud of his shiny new attachment. But when Bozer tells him it's needed on an important job, Diggs realizes that he doesn't know what it does; Diggs wears some new, fashionable treads, but his quest for fashion leaves Scooch in a tight spot.

When Bozer tells Diggs that he's full of good ideas he thinks he'll share them with Scooch and Carrie -- but Carrie has her own ideas, and they bicker; Diggs learns the merits of doing a job properly after he does mediocre work to save time.

Scooch is terrified to work on top of a tall building after spilling salt earlier in the day, as he believes it's a bad omen; Lug scoffs when he sees the new machines pretending to be a superhero named Big Rig, but he might need some of those powers.

When Diggs starts treating everyday jobs on the construction site as a competition, Bozer decides to introduce a real contest -- the Machine Challenge; On Maxine's mileage day, Bozer enlists the help of the others to organize a party to celebrate.

Carrie thinks she'd make just as good a boss as Bozer and when he gives her the chance she's determined to prove it; The machines must clear an old dumpsite to make way for a new car park in just one day.
