You know that castle thingy that you see on the titles of The Wonderful World of Disney, the one that looks all peaceful an' everythin'? Well, all is not as it seems. Inside the tower Mickey is fighting for peace, justice and the American way (although what peace and justice have got to do with the American way is beyond me).
Merlin the magician has had his magic wand stolen by the evil Ogre King. The wand has been split into four pieces and given to witches at the top of the towers in the castle. The ogre has put ghosties and ghoulies and things in the towers to try and stop you from getting the wand back together, but you are armed with a squirt gun and a hammer to deal with them. Eventually you just seal up the doors and stop them from emerging. This is done by entering a series of sub-games:
THE PUDDLE MAZE
Mickey must search for wood, hammer and nails to close the door up, whilst dodging or shooting the monsters.
THE BUBBLE MACHINE
Mickey stands on a randomly moving platform patrolled by a ghost. Bubbles rise from beneath and damage the platform if Mickey doesn't hit them with a carefully aimed hammer.
THE PUMP ROOM
This consists of a long pipe with corks at intervals. Mickey must hit the corks to seal the gaps and lower the forcefield guarding the demon, all the while dodging nasty monsters.
THE DRIPPING TAPS
Four taps must be turned off in a particular order via a system of moving platforms. Oh - and there's a nasty ghost as well.
At the top of each tower is a guardian thingie that must be shot in the head to retrieve a piece of the wand.
