In the tower, there is a purple ball you can kick around. There is also a fan you can activate on the mail building roof. Me and two friends worked together to it get on the roof and then one turned the fan on so the ball could be launched. Our destiny is complete.

Me and 2 buddies used the purple ball to push the bounty robot all the way by the far left wall. Hilarious watching people walk up looking for the bounty master xD
