We had literally nothing when we were here, so now that we have all the tools we are going to get, we can get absolutely everything here. You might as well use the Teleport dude right at the beginning here to go to "The Cannon" because this first section has nothing to offer us.
Work your way through this area up the pole covered wall and you'll find your first Cobweb. Now go up the tight ropes in this area and turn right immediately when you get into the area with the trapezes and you'll find another Cobweb blocking the Vault containing the "Oleander's Shame" memory.
Now what we need to do is get on top of this area where the Vault we just got was, first get on top of the bump where the Trapeze is and then use the levitation ball to jump on top of the area above the Vault. Now if you face back over the area we just came up from you'll see an airplane with a cage sticking out the front of it. Use the ball to jump over to here and walk through the plane to get the Purse.
From here look straight out and slightly to the right at the big brick stone wall, down this you should be able to see the last bright pink Cobweb. Jump towards here with the levitation ball and float your way down to the final web of this area. But there is still another area of Oleander's mind.
The first Cobweb to get in this area is right after the rotating room, then go to the final area of this level and right by the door (which is now all chained off) the last web is on the ground. Now it's time to go back to Sasha's Shooting Gallery!
