Solutions to Magic Land Dizzy

Needless to say, take all diamonds you find on your path. Also, keep track of
the locations and objects, as this isn't a walkthrough, just a solution.

Castle Backdoor: you can use the shark as a platform, but keep walking when
  it moves or you'll drop off. The door is opened with the backdoor key. You
  don't need the garbage or the milk bottle.
Ye Old Well: use the crank to get the bucket.
Haunted Swamp: while carrying the power pill, touch both ghosts.
Hot Water Geyser: use the bucket on the pool to fill it.
Throne Room: use Dora the frog on prince Charming.
Upper Hall: you can go east via the clouds and you'll end up in a treehouse.
Treehouse: there is a barely visible stick in the lower right corner. Also,
  you can go up, then to the top of the screen using some awesome jumping,
  then jump out eastward onto another cloud. This should put you on top of
  the Monolith, and a long leap east on top of Weird Henge. Keep trying!
Drawbridge: use the lever.
Trollbridge: use the stick on the goat.
Ice Palace Entrance: use the bucket of hot water on icy Denzil.
The Crypt: carry the cross or drop it near the witch, or she'll kill you.
Oubliette: give the drinkme potion to Daisy.
Upper Hall, left part: you can go west via the clouds to another treehouse.
Bard's Treehouse: give the personal stereo to the bard.
Ye Old Well: jump down, staying on either side of it.
Down a Well: stand on the right ledge, then use the flute.
Sword in the Stone: while holding the sticky stuff, take the sword.
Mirror Mirror: step through the mirror.
Chessboard: when you have Excalibur, touch the queen.
Curiouser and Curiouser: talk to Grand Dizzy.
Bushy Grove: use the dagger on Dylan.
Good Witch's Island: give the black cat, burning torch, leaf from Dylan and
  poisonous apple to the witch.
Bushy Grove: use the potion on Dylan.
Sleepy Hollow: put the lightning conductor next to Dozy, put the magic lamp
  somewhere, then pick it up while carrying the duster (or the other way
  around). Do this again and again until the genie goes mad and zaps Dozy.
Active Volcano: now that you've freed your family, you can go east.
Deepest Pit: speak to the devil.
Zaks's Tower: use the trident to kill Zaks, then take the ring.
Deepest Pit: speak to the devil.
Pits of Gehenna: use the ring.
Deepest Pit: speak to the devil once you've gathered all thirty diamonds.
The end.
