Act III (Wind Fountain Tour): In order to get to the Wind Fountain, Steve must be presented with golden tickets. However, he hasn't seen any in the time he has worked there. So, you need to work your puzzle-solving magic to make them. For this trophy, though, we have to cut corners. First: acquire the rolling pin by beckoning Steve and Pete. Use the rolling pin to set up the steps into the tour room. You'll also need the two pins from the drawing of the Wind Fountain and the brown tassel underneath it. In the visitor garden will also be a jump rope to help dangle your creation.
Combine the following together: brown tassel, pins, tickets, and the jump rope to get a false colorfly. Go back out to where Gorfelina is and disturb the Fosfos and the colorflies until they're on the left side of the scene. Return to the tour building and hop up the steps to get back outside, then throw the makeshift colorfly over to mingle with the real ones. The tickets will turn brown in the process, allowing you to access the special tour.
If you present the Golden Tickets to Steve before doing this, you won't be able to get this trophy.
