It's possible to reach the roof from the other side of the short building by skating up the colourful ramp and performing a Boneless (double-tap up on the d-pad + jump) while holding forward. The third bell is under a light on the side. Jump once more to stop grinding and then turn your attention to the red building. Once you're on this ledge, skate towards the wall and wallride along, then jump and hold grind to reach the roof. You can grind the top of this wall by jumping and then grinding. Make a sharp right and head to the blue table next to the brick wall. Next to the small wooden ramp at the bottom, on the red building, wallride once more to claim the second bell.

Once in the open area, bear left and skate down the slope. Continue forward, following the snaking walkway until it opens up again. Once you pass the pale gutter pipe on your right, get ready to wallride and grind across the first bell. Skate down this narrow alleyway, turning right at the end. Directly ahead there's a gap between the buildings on the right. Starting on the green roof, skate down and drop onto the floor.
