Trapped in the cave under the graveyard

Dizzy fell into the cave through the trapdoor, and the hole is far too high to jump back up to.
Nudge 1Where to look

Pick up the gymnasts bouncy trampet, carry it to the ledge under the trapdoor and drop it there. Jump onto it: each bounce sends Dizzy much higher than a jump. Steer left or right at the top of a bounce to land on the graveyard's ground beside the hole. (Hold down to stand on the trampet without bouncing.)
