Leslie, Ann and the rest of the Parks Department volunteer to help the organization KaBOOM! build a playground for a neighboring town. After building an entire playground in one day, Leslie gets frustrated at the progress with the pit, and takes some advice from Mark to cut through the red tape.

Leslie is upset when she learns the library department wants to take over her lot. Making matters worse, the library is run by Ron's ex-wife Tammy, who still has a powerful emotional hold on him. Meanwhile, Andy gets a job in hopes of winning Ann back.
