During your visit to the second planet, Sargasso, where you first play as Rivet (The girl lombax), you will have to fight the Seekerpede. After the boss battle with the Seekerpede, you will be able to free roam. Backtrack to your hideout towards the center of the map in the small tunnel (also adjacent to a Dimensional Pocket) and interact with the TV. Upon doing so, the trophy will pop.
