Scooch would like a bit more space in the idle house but Diggs and Carrie aren't giving an inch; When the young machines decide to tell stories, Scooch shows that sometimes the smallest truck has the biggest imagination.
When Lug tells Scooch that grading a road on your own is what every dumper dreams of, the little truck decides to do a bit of solo grading; When a daredevil dump truck comes to town, Scooch is thrilled to find out that Lug used to be one himself.
With Bozer off-site, Diggs mistakenly thinks Maxine has told him it's OK to do a job on his own; Carrie doesn't understand how to work her flashy new recharger -- so Diggs takes charge, despite the fact he has no idea what he's doing.
