Level: Lava Tube
Similar to the other two levels where you had to ride through an area, this Lava Tube just tests how often you can keep off the heated hazards. This one is longer and requires more precision to find the Scout Flies and Precursor Orbs. In the middle, you will need to keep your Zoomer cool while shooting five power nodes. As long as you stock up on enough Eco right then and there (don't pull more than you have to), you shouldn't need to gather all of them to take care of the targets. In fact, if you position yourself just right with one spot of Eco, you could take out all of the targets by simply shifting your Zoomer to the left or right while staying in position. After that, you will open the gate and get to progress through the lava chute.
The earlier part of the path will see your Zoomer heat up quite frequently. If you make use of the elevated ramps, you can use R1/L1 to jump and give yourself some time to cool outside of using the balloons.
