Level 1-1: To find Level One's secret passage jump Down from the second
angled ledge and go underground. The first passageway to the Left has a
false wall which Mickey can pass through. At the end of the passageway
there's a variety of bonus goodies.
Level 1-2: Go to the cliff by the forth rope and drop off the Left side
while holding to the Right and you'll get ten apples!
Level 1-4: Jump into the hole by the fifth tree and walk to the Left through
the rocks to find a room with a free mouse and two stars.
Level 3-1: There's an identical secret passageway, just before you go
underground. Proceed just as in Level 1-1 and you'll find another false
wall and goody room.
Level 4-3: When you find a tea cup, jump in for a swim and you'll find all types
of power-Ups. Be careful of the sugar cubes!
At the end of the second level in Toyland, you'll come across a bag of
marbles. If you pick the bag up and proceed to the Right far enough,
when you go back to the Left, the bag will reappear. Each time you pick
the bag up, you'll receive 1,000 points and extra marbles (up to 30).
As long as you are on the vines in the second part of level 1-1, you're
invincible. Swing on the vine and get all the points you want and up to
ten men. You'll average about 95,000 points an hour.
