The rooms upstairs in the trolls' castle
The trolls' castle's upper floor is split into rooms by thick walls, and its floor has gaps everywhere. Walking along it gets Dizzy nowhere.
Nudge 1Where to look
The rooms are reached from below: from the reception hall's high ledges, a jump up through a gap lands in the room above.
Nudge 2A stronger push
For the left room, jump up from the hall onto the little block under the gap on the left, then up into the room; a small step on its floor leads to the high ledge in its corner.

Go back down into the reception hall and climb its ledges to the one under each gap; jump up through. In the left room, use the small step to reach the corner ledge with the complete d.i.y. rope bridge kit (A box of bridge). The middle and right rooms have stars.
