I was crouched behind a luminous bush, heart thudding like a stolen drum. A pair of pink and blue spotlights marked the hill—so obvious I almost walked past it. Walter, meanwhile, had already forgotten where he hid the present.
I’ve spent hours following half-remembered riddles and teasing apart sloppy clues for games on Steam and Switch, and I’ll walk you through Walter’s two treasure notes so you don’t waste time circling the wrong island. You’ll get the key, the second note, and the Twinkledust without guesswork—so you can focus on finishing Dragon’s cake.
The cove is under the hill with the giant pink and blue lights. Treasure note 1
Observation: the landmark is loud—a tall building with twin spotlights you can see from most of the map. If you can spot those lights, you’re half-way there.
After talking to Walter, he hands you Treasure Note 1. It reads: “In a green cove, cozy and bright, where hearts align, near disco lights! Behind soft leaves, the way is near… Walk straight through, do not fear!”

How you find it: fly to the hill with the tall building and two giant spotlights. There’s a small cave entrance carved into the side of the mountain—framed in greenery and dotted with faint blue lights. That’s your cove.

Walk through the green bush to the right of the star. It feels like passing through a backstage door at a concert—sudden and surprisingly ordinary—and behind it you’ll find two glowing items: Walter’s Key and the second treasure note. Pick them both up, then check your inventory for the next clue.

Where is Walter’s treasure hidden in Duck Side of the Moon?
Short answer: the second note points to the blue island with the train station. The word “travel” in the riddle is your signal—there’s only one place on the map that fits.
The blue island is near the train station. Treasure note 2
Observation: the blue island is the only travel hub on the map; the station’s platform is visible from space. That makes it the logical spot for anything involving movement.
The second treasure note says: “Inside the blue island, it hides… where geodes travel far and wide! Look to the right, beneath a tree. A locked door for you to see!”

How you do it: fly to the blue island, then circle the platform until you spot a ledge beneath one of the red trees. Approach the opening and you’ll see a thin wooden door. Use Walter’s Key on it.

Inside is another walk-through bush—this one red. Push through and claim the Twinkledust, the item Walter misplaced. It looks sharp and golden; once it’s in your inventory, you can take it to the baker to finish the cake for Dragon, or continue to the quarry if you still need miner gifts.


How do I use Walter’s Key?
Equip the key from your inventory, approach thin-planked doors (the ones tucked into ledges under trees), and interact to open. The prompt is obvious on Switch and Steam controller layouts—if you play on PC, use the interaction key shown in the HUD.
Where do I take Twinkledust to get the gift for Dragon?
Take Twinkledust and any miner gifts you’ve collected to the baker NPC. If you’re missing miner gifts, head to the Quarry first and finish those optional tasks—then return to the baker. The process is straightforward and mirrors many quest flows you’ll find discussed on Reddit and Discord channels for Duck Side of the Moon.
If you want a quick checklist: 1) Talk to Walter and get Treasure Note 1. 2) Find the green cove under the pink and blue lights. 3) Walk through the green bush to get Walter’s Key and Note 2. 4) Fly to the blue island train station, use the key on the wooden door, pass the red bush, and pick up Twinkledust. Then finish up with the miners or take everything to the baker.
I’ve guided players through obscure puzzles on Steam forums and written step-by-steps for console players—this one’s short, intentional, and forgiving if you’ve missed a chest. So, will Walter ever remember where he hid the rest of his gifts?
