Split
Once the purple button is pressed, you need to use the other seaweed gates to split up the Jellyfish such that at least one Jelly makes it into each area. Step on the green button first, and wait until three Jellyfish have passed the green seaweed, then switch onto the yellow button. Now wait until the middle of these three Jellyfish is on the second yellow seaweed patch (circled) before switching to the red button (this will guide one Jellyfish each into the two upper areas). Once three Jellyfish have safely passed the red gate, step onto the blue button. Again, once the middle of these three Jellyfish is on the blue seaweed patch it is time to step off the button in order to split this group. Now make a dash for the Bonus Bubbles before the Krabby Patties are collected.
