Where is the jet pack in Cyberchase race for radopolis quest?

First, get the last possible thing that you can get in the gift shop when you go to the donut museum. (I forget what it's called though) Then you have to go to radopolis and talk to the gennie buy thingy that comes out of a magic lamp. To find him just walk around radopolis until you see a little blueish thingy on the side of the road, then click on it and he will come out. Make the trade with him and you have your jet pack.
