Ethel Anderson is hired as a new park ranger, who shows a passion to save the mediocre state park of Brickleberry. This makes Steve afraid that she is going after his "Ranger of the Month" award. Meanwhile, Malloy goes on a new diet.
When Woody is looking to have a cute animal represent Brickleberry, Steve mates a squirrel and a rabbit together, creating a squabbit. Then the squabbits begin reproducing uncontrollably to the point where the park is overrun with them, and chaos is let loose over Brickleberry.
Woody tries to impress the Secretary of Interior by secretly setting the park on fire, to then put out himself. Connie is surprised by the sudden visit of the Secretary, and we learn more about her troubled past.
The rangers discover that Steve wears a toupee while they prepare for the annual Ranger Ball. In an effort to re-grow his hair and feel better about himself, Steve becomes Bigfoot which makes him a sudden celebrity.
The dam that holds back Brickleberry River is destroyed by fireworks set off in honor of Woody's birthday. The park floods and the rangers, along with the rest of the survivors, must re-form society on the island.
