Artsie Trophy
To collect the Artsie trophy, first go to the bayou. In the jungle area with the plants that eat you, go across the bridges all the way to the left, until you reach an area with two man-eating plants. Disable both (press B when you are caught in the vines) and keep going. You will go under the trees and the arrow will appear. Press A for the Artsie trophy.
Voila!
p.s. Giving the trophy to Roxanna Moxie will give you a free rep point.
