Diggers Split Up is the twentieth episode of Recess's fourth season, which was first broadcast on November 19, 1999.
The Diggers have a fight and split up. It falls on the gang to get them back together.
The day starts as peaceful as can be, but just then, the diggers are arguing, and Dave decides he has had it, and he storms out of the hole. The next day, Gus falls into a hole dug by Sam in front of the school. The gang then encounters Dave, now quitting digging and wearing a more casual outfit. During that day, Dave starts to boss everyone around crazy, even telling Upside-Down Girl how to hang upside down.
Sam is digging everywhere, and he can't seem to know where to dig next. Gretchen pieces it together, Dave doesn't have Sam to boss around so he bosses everyone else around, and Sam does not have Dave to tell him where to dig, so he just digs everywhere without a distinct purpose. So the gang tries to get them back together. Their first attempt fails, so they stage a plan. Some of T.J.'s friends tell Dave that Sam is trapped in a cave in, prompting Dave to try and save him. It turns out that Sam was having a break with Spinelli, and that the gang filled the hole in themselves. The diggers reconcile, and the gang then goes to enjoy their recess.
