How to complete Robbie’s “Bucket List” in Wuthering Waves

Bucket List is a hidden side quest in Wuthering Waves set in Sundermere, built around a damaged Mechascout named Robbie and its last requests before it shuts down. The quest is short but structured, with a few mechanical requirements, a puzzle, combat, and a final sequence that awards Astrites and the Robbie’s Dream trophy.

How to unlock the Bucket List quest

Rebuild the Submerged Tunnel in Sundermere. The quest will not appear until this tunnel has been constructed.

After the tunnel is rebuilt, head to the nearby relay station.

Use the in-game time feature to advance the clock by a few days. You can adjust the time from the usual in-game interface, where time skipping is allowed.

Wait for a WavesLine message from an unknown sender. Once this arrives, a prompt will lead you to speak with a Mechascout named Robbie, which formally starts Bucket List.

Reach Robbie in the Submerged Tunnel

Track the new quest marker and ride your bike into the Submerged Tunnel. The navigation will lead directly along the tunnel route.

Continue riding until you arrive at Robbie’s location. Interact with the Mechascout to begin its set of wishes and learn that it is heavily damaged.

Find Robbie’s parts and defeat the Ironhoof

After speaking with Robbie, follow the updated quest marker deeper into the tunnel area using your bike.

You will encounter an enemy named Ironhoof. Engage and defeat this target in combat.

Once Ironhoof is down, collect the required parts from the marked spot and return to Robbie’s position.

Interact with Robbie again to install the recovered components and stabilize the Mechascout, which allows the rest of the quest to proceed.

Use the Smartprint Cube and heat the hot spring

Robbie wants to experience a proper hot spring, which requires restoring a device via a Smartprint Cube puzzle.

Go to the Smartprint Cube indicated by the quest navigation and interact with its interface.

Input the required directional sequence exactly as follows:

Right ×4 → Down ×2 → Left → Down → Right

Completing this pattern prints the device and activates it, which heats the nearby hot spring. You also receive 15 Astrites for solving the puzzle.

Visit the hot spring with Robbie

Follow the quest marker to the hot spring Robbie mentioned earlier.

Speak with Robbie at the hot spring to trigger a cutscene of the two of you using it.

During the scene, Robbie asks about electrical stimulation. Use the Echo Projector utility to discharge an electric current into the hot spring. The prompt appears near the pool; activate it while an appropriate electric Echo form (such as Zap Zap) is selected so the current is applied correctly.

Help Robbie change its Mechascout livery

Next, Robbie wants a new look before its systems fail completely.

Move to the marked location and interact with the Livery Applicator device.

After the dialogue, follow the quest marker into the surrounding area and collect the required plants. These plants provide the pigments used as paint colors.

When you have gathered all the materials, return to Robbie.

Talk to Robbie once more so that it can begin applying the new Mechascout livery using the plants you collected.

Return to Sundermere and fulfill Robbie’s last wish

The final wish on Robbie’s list is to reach the sky and see the world from above the clouds.

Go back toward Sundermere following the new quest marker, then mount your bike when prompted.

Ride along the indicated route, climbing higher until you reach the top area “above the clouds” that the quest directs you toward.

At the final point, a prompt hands direct control of Robbie to you. Move Robbie to the edge of the cliff.

Jump from the cliff as Robbie. This triggers the closing cutscene that resolves the story of the Bucket List side quest.

Once the cutscene ends, the quest completes. You receive 20 Astrites and unlock the Robbie’s Dream trophy.

Bucket List sits alongside other late-game Sundermere and Lahai-Roi content as one of the more emotionally heavy quests in Wuthering Waves, but mechanically it stays straightforward: rebuild the Submerged Tunnel, respond to the WavesLine message, clear a single notable combat encounter, solve one Smartprint Cube pattern, and follow the markers through Robbie’s final wishes until the trophy pops.
