Collect all three Green Stars in Battlerock, Buoy Base and Dusty Dune to reach the Planet of Trials. Bubble Blast is the longer bubble-control trial and has one Power Star.
The Electric Labyrinth
Enter a bubble and use the pointer’s air blower to move it. Short puffs give better control than holding the blower continuously. The opening section requires five Star Chips from the separate branches. Follow each branch through its electric obstacles, then return to the central area before taking the next one. Stay near the middle of a corridor and let the bubble settle before changing direction. Touching an electric rail or mine bursts the bubble.
Finish all five branches
Use the chips as your progress checklist. Check the remaining branch entrances if the Launch Star has not appeared; collecting ordinary Star Bits does not count towards the five chips. In a moving obstacle section, stop pushing early and wait for the opening to pass in front of the bubble. A gentle pulse through the opening is safer than approaching at full speed and trying to brake at the last moment.
The final bubble course
Once the five chips form a Launch Star, take it to the last section. Enter the next bubble and follow the narrow route around the electric boundaries. Keep looking ahead for mines and approaching hazards, and avoid hugging a wall even when it appears to shorten the corner. Use small steering bursts through the final bends, reach the safe ending and collect the Power Star. This is a precision challenge: there is no extra star for completing it faster.
