This galaxy is available once you have access to the Planet of Trials, which is unlocked by collecting the three Green Stars in levels Luigi under the Saucer, The Secret of Buoy Base and Treasure of the Pyramid. This galaxy appears to be a trickier version of Bubble Breeze Galaxy.
The Electric Labyrinth
Throughout this level, you’ll need to travel around the galaxy in a bubble. This is trickier than it might first appear as there are lots of things that could pop your bubble and cause you to be sucked into the black hole beneath!
Floating in a Bubble
When you’re in a bubble, you’ll need to use your star cursor (which looks like a little horn when you’re a bubble) to blow air and guide the bubble along. If you hold down A you’ll blow lots of air and the bubble will go faster, but if you want more precision and accuracy, tap A to move the bubble in a more controlled manner.
Electric rails - In this level, you’ll need to avoid the electric rails by steering your bubble around them. If you hit one, your bubble will pop and you’ll need to begin again!
Amps - Amps are electrical black orbs that move along a set path. They are not animate, but will damage you if you touch them. If you hit one whilst in a bubble, your bubble will pop and you’ll have to begin again.
Fire Pressures - The fire pressures in this level are on a timer and will turn off for a short time. They are indestructable
Floating Mines - Floating Mines will explode and damage you upon impact, so make sure to steer clear of them!
Bullet Bills - Bullet Bills will lock onto you like a homing missile. The best way to get rid of them is to guide them into obstacles so that they explode into them instead of you!
