Sensei's Lost Castle

Ride the balloons down to items on either side.

After Catapulting yourself onto the wall, leap to the nearby tree for an Object. Now return to the catapult and push it as far right as you can, then launch from it to hopefully reach a ledge high up on the right for an Object and Sticker. Once inside the castle, work your way to the second floor (accessible by the first staircase) and look for a hidden path in the wall (where the enemy comes from) for a Material. When you reach the large spinning wheel, grab hold and ride it around for a Sticker. After jumping to the ledge above the first wheel, look for a room to the left that contains four Sticker Spots--Plant the Blue Mountain and Japanese Wave stickers there to reveal 2 Objects and 2 Stickers.

As you climb your way up several more wheels, jump from the second wheel closest to the top toward a Sticker on the far right. At the next checkpoint, head left to find a Material behind the wall. At the balloon section, jump to the far right (before dropping down) to find a Decoration. Now grab hold of a balloon and float down to a ledge on the left for a Material, then another just below for a Sticker...and another Sticker on the ground level. There's also an Object on a far right left, so you may have to kill yourself in order to return to the previous checkpoint and grab another balloon.

When you reach the large wheel (past the balloons), grab hold and follow it around for an Object below, then leap from the top of it for a Key, and 3 Objects. Inside the shaft with the numerous spinners, you'll find 2 Objects and a Sticker as you work your way up--you can reach them by leaping from the spinners either below them, or to the sides. As you swing across the electrified chasm on the ball, you'll automatically collect an Object.

When you reach the ball on the track, grab hold, then drop down a level and head left for an Object. Look for Sticker on the right on the level below. Once you reach the very end of the track, it should swing you right into a Material.

As you traverse the corridor (just after the ball track), you'll find an item inside a pillar. Afterward, Bounce off one of the enemies to reach an Object. Soon after, you'll reach another shaft with some green wheels. Ride the bottom one around for an Object, then leap from the very top one to reach an Audio Object and Key. In the hall with the two large enemies, bounce off one to reach an Object in the center alcove.

After defeating the sumo wrestler, you'll have to grab hold of some friendly creatures who'll bounce you up a shaft. Look for an Object on the second platform from the top. When you grab hold of another roller soon after, ride it along the tree branches slowly to ensure you grab the 4 Decorations, and 1 Sticker along the way.
