Talk to Old Fisherman by the Pond
- If you're on the splitting screen, click the Exit door icon in the lower-left corner. Wait for the transition back to the outdoor 3D world.
- Go to the wooden dock by the pond. Look for Old Fisherman, the NPC wearing a red hat with a long white beard.
- Use E: Talk, then select NEXT to read his dialogue. His clue points to a cave beneath the windmill, where he left a lantern.
For the lab's other controls, see the Mitosis beginner guide.
Find the Windmill Cave and Light the Chamber
- Head toward the windmill, using its stone steps and the nearby water channel and waterfall as landmarks.
- Move around and below the windmill platform to the terraced grassy slope. Look for a low black opening in the gray rock, beneath the brown soil and grass, beside blocky green vegetation. Approach that opening's area to reach the underground chamber.
- Follow the yellow glow on the chamber floor to Broken Lantern. Hold E: Pick up until the interaction finishes. The lantern lights the chamber.
- Find the sealed double door with the yellow duck emblem and read its clue: bring back all the Duckies hidden around the island.
- Return to the hanging Rope and hold E: Climb out to get back to the surface.
Collect 12 Duckies and Check These Locations
Walk into yellow Duckies to collect them; no interaction key is needed. Each collected duck disappears and advances the DUCKIES counter on the right.
Start your search at these three locations, then explore the rest of the island until you've collected all 12:
- Below the windmill: Check the cliff-edge grass beside the water channel, near the cave's terraced slope.
- Across the island bridge: Head toward the small island with stone pillars and a green orb. Look at the far end of the wooden bridge, near the island entrance.
- Beside the central fountain: Find the green fountain topped by a large red ball. Follow its paved outer walkway and look beside a lamp and bench.
Use the counter to track your remaining Duckies. At 12/12, you'll see THE FLOCK IS WHOLE! and RETURN TO THE SEALED DOOR.
Open Temple Door and Claim Rubber Duckie
- With all 12 Duckies collected, return to the cave beneath the windmill and head to the door with the yellow duck emblem.
- Use E: Read on Temple Door to open the passage.
- Enter the camp beyond the door. Talk to @onlyoba near the campfire; he directs you to the chest behind him.
- Find Old Chest in the corner and use E: Open to claim the Rubber Duckie Exclusive Skin.
The yellow Duckies are the quest collectibles. Rubber Duckie is the ball skin rewarded by the chest, transforming your ball into a red duck. Reaching the collection target opens the way to the reward; finish by opening the chest.
