[Want to see more guides like this? Subscribe to GuideRanx for daily new gaming guides.]

The collectible hunt continues as we enter World 2 of Donkey Kong Country: Tropical Freeze. Autumn Heights is a charmed mountainous island filled with fall delights like piles of dead leaves, snowy peaks, and charming villages full of angry little penguins. Once again, we’re delving into all the treasure locations — KONG coins, puzzle pieces, and secret exits leading to bonus levels.

Like the first world, you’ll find two secret exits, and a KONG bonus level. Find all the KONG coins to get the level, and the bonus levels tend to be just a little more difficult than the regular levels. They even have their own KONG coins to get. Well, all of them except the final bonus level. You’ll just find puzzle pieces (which are still cool) in those stages.

All Puzzle Pieces, Secret Exits & Kong Letters Collectibles | World 2: Autumn Heights

There are four K-O-N-G letters in each stage, and a variable number of puzzle pieces. Finding all the KONG letters will unlock bonus stages in the world.

Puzzle pieces unlock additional concept art in the “Extras” menu. Puzzle pieces are often in secret areas, rewarded for completing bonus areas, or given when collecting certain bunches of bananas.

Secret Exits are special exits to levels that take you to new, completely unique levels. If you’re missing a level in the world, it’s because you need to find a secret exit.


2-1: Windmill Hills

  • Puzzle Piece #1: Right at the start of the level, knock down the wooden logs and grab a barrel. Throw it at the target to the left of the starting point to enter a mini-game with a puzzle piece reward.

  • Puzzle Piece #1: At the start, hop over the first bed of spikes and enter the hidden door under the wooden platform in the rocks. Complete the mini-game for a piece.
  • K Letter: On the rocket barrel, stay in the center and navigate so you can position yourself in the missing wedge on the rolling cheese wheel. It’s right past the first swinging cheese.

  • O Letter: Stay on track and avoid the thrown cheese wedge. The letter is right in the center of the path.
  • Puzzle Piece #3: Further ahead, you’ll reach a cave that’s lit up with spotlights. Get all the bananas on the path with the first three spotlights.

  • Puzzle Piece #4: Right before the pig checkpoint stand, stay low to grab another puzzle piece in the dark zone.
  • G Letter: Pretty tricky! At the end of the spinning giant cheese wheel gauntlet, stay in the center and align DK with the missing section of the wheel so you can stay in (about) the center and collect the G. Easy to spot, but hard to collect.

  • Puzzle Piece #3: You absolutely need Dixie ahead. After launching and bopping off bird heads, you’ll land on a pillar with a hanging platform to the right. The puzzle piece is directly beneath the platform. Jump under it and use Dixie to reach the safe platform.
  • Puzzle Piece #4: Later, you’ll land on a falling platform with a series of flying birds between burning blue enemies. Pause and wait until another bird zips up from below with this puzzle piece.
  • Puzzle Piece #5: At the spinning platform, you’ll have to move fast again. Launch and immediately drop down from the platform before the spinning wheel moves the enemy / puzzle piece off the map.
