Everyone is confused, kinda chattering amongst themselves why, and Dr. He tells them that no matter what happens that they are not to press it. Langer says 'be yourselves, my scientists will observe you.' There is one more thing he whistles, and a button comes in somewhere from the top. Mordecai asks what they must do this time, to which Dr. Langer tells then that they are not trapped this time, and gestures to an in and out door by the park. Fives asks him to tell them what's going on, and Muscle Man asks why they are trapped in the dome again. Langer dismisses it, saying he has their names from the last time. Benson is about to introduce everyone, but Dr. Langer) comes in from the sky on a jetpack, saying they are back indeed, doing more experiments that won't be (too) deadly. Mordecai wonders why it's back if they got rid of it before, and suddenly a scientist (Dr. Benson thinks he won't because it's a long drive however, Skips turns his head towards the dome, telling him to look up, to which Benson replies with a simple 'No.' before saying it twice again, but more panicked. Benson tells Pops to go look for branches and Skips to go get a new kit the latter responds that it's not going to happen. Everyone else does notice, and is struck dumbfounded, starting at it. It seems the dome has returned, but Benson doesn't notice this, starting to talk about an aftermath meeting instead. Mordecai and Rigby believe they have survived, to Benson's anger, who yells at them to go outside. Benson then comes, demanding wanting to know what they're up to, but a large raft inflating cuts him off.

After, Rigby eats the gorp and Mordecai throws a flare. Mordecai drinks all the water in the cooler, and Rigby begins wrapping his head with a bandage, as well as putting some smaller ones on him. Upon opening it, they take out some whistles and blow. They burst into Benson's office, looking for the Emergency Earthquake Kit.

Awoken by this, Mordecai and Rigby come to a conclusion that it must be an earthquake. Everything falls on the floor, including the coffee maker, the weight on Skips's barbell and Pops's ship-in-a-bottle. Soon after, however, everything starts to shake.

The show starts with Benson getting some coffee. The guys need to protect a large red button from being pushed.
