By the time you reach Happiness Research Lab, you should have a pretty solid idea of how this stage is set up. Explore the map and clear out the Fuzzy Ooze in your path. The missions in this area are some of the toughest in the game, but you don’t need to complete all of them to take on Big Man and continue with the story.

If you’ve collected all of the Sunken Scrolls up through the Eco-Forest Treehills, then you should have 20 before you reach this point. It will take a few thousand Power Eggs to reach the point marked on the map above, but once you do just shoot the crate on the island and the Sunken Scroll will pop out.

Ride the rails from the scroll above and you’ll quickly reach the island marked on the above map. There is some Fuzzy Ooze here. Clear it out and it will uncover the next Sunken Scroll.

Sunken Scroll 24

The final Sunken Scroll in the game comes in the form of a Green Balloon challenge. You’ll need to clear out all the Fuzzy Ooze that you can before you set off on this challenge. You’ll need to ride the rails around the level, chasing the balloons as they appear. Because the rails are only one way, you only get one chance to hit these balloons or you’ll have to start right back from the beginning. Be accurate and you will get a Sunken Scroll for your trouble.
