Bonus screen
Complete 100% of the game (all tasks completed in each level, all costumes unlocked, all special moves unlocked) to view a screen featuring the characters in the game.
Defeating Merlock
When one part of the floor shakes, go to the other part of the floor and dodge the fireballs. The pin-like things being shot from the front are harmless. When he splits up into four forms, hit the one whose pendant glows and repeat. Use caution because the less energy Merlock has, the more floor tiles fall into the lava.
Infinite Super Milkshake
This cheat is activated by typing "qbdou" during any normal level (not during chase or boss levels). When activated, Donald will permanently run as if he is under the influence of a milkshake, but several times faster. Donald cannot be hurt in this state, except by falling into a pit. To disable the cheat, type "fouqd". This is necessary to exit a level.
Special move
Quickly collect five cogs to get one letter from the word "SPECIAL" in any level. Keep collecting cogs until the entire word is spelled out. Complete the level to learn a special move.
