Peter and Rocket installed one of the Thumpers. Background: A destroyed Nova Corps vessel and Nano-Resin.
Thumper is a contraption built by Rocket to lure a monster to a designated location in Chapter 1: A Risky Gamble. The crew must place several of them in the instable The Quarantine Zone.
- According to Rocket, this thing does a screaming loud "WAAH WAAH WAAH" sound, which he demonstrates with his mouth on the Milano just before they begin the mission.
- At the end of this chapter, when the last thumper was installed, Rocket will hold his ears from the annoying sound, but the others won't be able to hear it.
