The second stage introduces grassy platforms, which you can cling onto by holding or (or , if you're holding the Wii Remote horizontally). While clinging, you can move freely along the grass, and jump straight off to reach items and platforms.
At the beginning, there is a pit of spikes to cross over. It's too wide to jump over, so jump up and cling onto the grassy platform above. Move across it and drop down.
After collecting puzzle piece #3 and jumping over a few platforms, you'll find a single yellow gourd between two narrow bridges. Pound it to make a barrel appear, then shoot off to the background to find the O block and the fourth puzzle piece. Use a barrel on the right side of the platform to return to the foreground.
K: After the spike pit at the beginning, use the stone platform to jump onto a platform with a DK Barrel. Break it, then jump right to grab the K block.
O: Once you've shot off to the background, use one of the small grassy wheels to jump to the O block.
N: After puzzle piece #6, climb up until you reach two grassy wheels. Climb on them and cling onto the rightmost wall. Move downward without letting go to find the N block. Afterward, jump on the platforms to the top-left.
G: Near the end, you will encounter a series of flower platforms. On one of them is the G block. Carefully time your low- and high-jumps to avoid getting hit by the enemies, grab the block, and jump all the way up to the end barrel.
Jump back to the platform where you found the DK Barrel, and use Diddy Kong to hover-jump to the right. Hover into the top-right corner to reveal the first puzzle piece.
Jump down and continue to the right until you come across a grass-covered wheel. Cling to the wheel and jump onto a platform to the left. Jump left from here into the top-left corner to find a secret piece.
Right after the grassy wheel, jump onto a platform floating above a spike pit. Use Diddy to hover-jump to the top-right corner.
While you're in the background (where you got the O block), use one of the wheels to jump and cling to a large, grassy rock. Climb your way up to the top to find a barrel, which will take you to a bonus stage. In this stage, you must use the platform at the bottom to bounce and collect all of the bananas and banana coins. Collect all of them within the time limit to get a puzzle piece.
When you are clinging to a grassy platform above a giant chomping plant (right before the checkpoint), pound on the gourd in the middle to reveal the fifth piece.
After the checkpoint, climb a grassy wheel to a platform on the left, and jump up to the suspended platform above that. From here, jump to the right into a secret space that contains the next puzzle piece.
The final puzzle piece is near a bouncy flower platform. Before jumping up to the next wheel, move to the right past the platform to reveal a hidden area with the piece.
