Instructions
Travel west in Tulgey Woods until you see a purple watermill. Switch to the White Rabbit and press any button to activate his Time power. Tap the "Rewind" button with your stylus to reverse the direction of the watermill, bringing the raft closer.
Jump onto the raft and activate McTwisp's Time power. Tap "Fast-Forward" to reverse the watermill's direction and bring you to the other side. Continue west until you see a stack of playing cards blocking the way, then blow into the DS microphone to collapse the deck.
Walk past the teleporter, over a bridge and then switch to the Caterpillar at the ravine. Tap the first green circle and then the other circle to stretch the Caterpillar's bridge over the gap. Defeat the charging red knights, then switch to McTwisp. Use his Time power to fast-forward the blue plant and make it grow into a tree.
Climb the tree and move to the right of the screen. When you see a card windmill with broken arms, use McTwisp's Time ability to rewind time and fix the cards. Blow into the microphone to set the arms spinning, knocking down the tree.
Continue east, then switch to the Caterpillar at the green mist. Tap the "Up" button to float up, then head left, past the attacking red flowers to the blue-striped tree. In the cutscene, the Cheshire Cat joins the group.
Switch characters to the Cheshire Cat and activate his Invisibility power. Tap the black square to make the bridge visible. Cross the bridge to the other side and pick up the puzzle piece to Tulgey Mill.
