Bentley: Okay Sly, this one's seem pretty simple - Tail Grizz until you can get the code to his fortress. We need to get in there if we're going to stop him. You shouldn't have any trouble finding him since he's tagged with the homing darts. Just follow the signal.
Sly: We probably didn't even need the darts. He's kind of hard to miss.
― Job briefing[src]
In this mission, Sly follows the Grizz around the valley in order to obtain the codes to his mountain base. In the meantime, Grizz talks to Le Paradox on a high-tech phone, attempting to get more supplies for him so he can keep producing paintings for his pre-historic art con. After Sly tracks Grizz to his base and Bentley fails to get the code, Grizz goes into the base. The gang then thinks the mission is a failure until Carmelita shows up and tells Sly she has the security codes and full schematics for Grizz's mountain base. Sly thanks her and the two go back to the safe house to formulate a plan of attack for the Grizz.
