After using Spidermonkey to grapple from one scaffolding building to another, drop down through the hole on the left and go around the right corner to get the first card.
After Kevin gives his perfume idea, you will have to use the scaffolding to cross a gap. On the lower part of the scaffolding is the second card
In one scene, you will get instructions to clear the path before going through. Before doing anything, drop down and go ahead before going right to get the third card
Final Battle[]
After defeating a bunch of enemies, you will need to break a wall as Humungousaur. After this, you will need to swing across as Spidermonkey. While swinging, swing and jump a little high to obtain the first card
When you come out of a building there will be a small vent in the background. Move through the vent to find some people to be rescued. In this room, behind some boxes is the second card
You will eventually come to a puzzle using 2 blocks and a rotating crane. Once you make it to the other side there is a save point. In that same room, there is a wall safe hidden behind a crate. Smash the crate and melt the safe as NRG for the third card
