Wait in the queue patiently
(This is a 2 player game). Flick the switch when the Coral is in the position highlighted to turn all of the anemone PURPLE. If you miss a hit, they will reset. Do this until the glowball moves back and you can move off the chair.
Flick the switch and run through the seats in front of you, if you are too slow the seats will move back and you will be teleported to the switch again.
Note: After the second lot of seats you run through there is a hidden switch for a hidden badge.
Walk only when the Coral and Anemone are in the state/colour highlighted below.
Sit on the bubble seat, it will move. Follow it round the path and get to the end.
