While you may be on a mission to save the world of Riverside from almost certain destruction, it doesn’t mean you can’t help out a few friends with a side quest or two! One such character who could use Ruffy’s help is Lux, the crow scientist perched up high in Central Riverside, who is struggling with his Northlands research. So here is our Ruffy and the Riverside – Lux Guide to help you gather intel for Lux, and unlock the I Am A Scientist Now achievement.

Lux’s Lookout
Lux is situated on top of a tall spire of rock near the gorge in the North of Central Riverside, and it takes a bit of preparation to reach it.

In the crater with the geyser of lava is a wall puzzle. Solve the riddle to make the portal to enter it.


Before hopping through the portal, use the Swap on the worm creatures in the wall puzzle to make them all short.

You’ll also need to use the Swap to change the directions of the arrows; otherwise, you will hit the spikes.

Get to the end of the wall puzzle to knock an ice orb out of it. This will roll down and freeze the lava into an icy platform.

Ride the ice geyser up and jump to the floating island with the Turbo Tube.

Use your Swap to change the Turbo Tube’s colour to red with the tree’s leaves, then hop in.

You’ll arrive on top of Lux’s Lookout, and he’ll be so impressed with your use of the Turbo Tubes that he will ask for Ruffy’s assistance.

He tasks Ruffy with helping him fill out his research on the Northlands.

Thankfully, you won’t have to go far to get the intel you need; in fact, it’s all in Central Riverside! Three exclamation points (!) will appear on your map, showing you where to go.

You want to hop down to ground level and look for little colorful birds sitting on tree stumps. They have interesting things to share with you, and some of it is about the Northlands.
The first one you are looking for is by the small river that runs past the forest area in the West of Central Riverside.

The second bird is along the cliff edge, northwest of Lux’s Lookout.

The final bird is just before the entrance to the Northlands, over the rail, so you will need a hay bale to reach it.

Return to Lux and his telescope to deliver the information.

Lux will thank Ruffy for his help and reward him with a Dreamstone. You will also unlock the I Am A Scientist Now achievement.
