Part 30

Start by jumping on the first fan and collecting all the bananas that pop out. If you collect all of them, you will receive a puzzle piece.

Continue right until you see a fan with a broken blade. Ride this fan to the left and jump to the platform on the left to get the 'K'.

To the right of the next fan, jump onto the hanging platform. Jump off this platform to the right, passing over the wall to get a puzzle piece.

Continue right to a barrel cannon. This will launch you into the background, where fog obscures vision. Navigate the series of platforms; the bottom one holds the 'O'. Be cautious as platforms are hard to see.

Checkpoint #1.

Jump left off the current platform and continue across the smokestacks. A puzzle piece is located on the third smokestack.

Head back right to a fan. Turn the fan to raise a nearby wall, then jump into the barrel cannon.

In the background, above the second moving platform with a hook, a puzzle piece is hidden by fog. Use the platform on the right to blow the fog away and then jump to grab the piece.

After returning to the foreground, the 'N' is above the first platform. Jump to grab it.

Checkpoint #2.

In the next area with tiki zings, take the high path to the right. Jump through the wall emerging from the top of the screen to find a hidden area with a puzzle piece.

Jump right off the platform in the hidden area to find the 'G'. This requires more height than a ground jump, so if you miss, return to the hidden area.

Blow into the megaphone at the right end of the current platform to reveal a puzzle piece.

The broken fan to the right has a puzzle piece on its top-most platform. Jump up to get it.

Continue right to a large, red button. Ground-pound it to clear the fog from the factory. A blast barrel will appear, launching you to the exit barrel.
