The players arrives to this spiral-looking maze composed with blocks. The whole zone is a non-drag zone. At the center of it rests a single core. Four inactive emitters (or they could be active) are around the spiral.
The player must first activate the four emitters to be able to flick a bubble in the spiral, which will get to the core thanks to the new ripples.
Now that the core is activated, the emitters start moving around, thanks to blocks that are pushing them.
The player must now time his flicking in a way that the bubble will get to the core. The bubble must also be of the right size, since if it loses too much momentum of does not, it will the right timing spot.
