Flying Goobers
Welcome to Sandy Beach. There is a new type of tentacle here - watch out for the goobery balls that they fling at you. Time your steps carefully.
Collect the Krabby Patties around you first, then move along the blue path (ducking into the alcoves to avoid the tentacle fire) to reach the Bonus Bubbles. Now push the wood box along the purple arrow - the tentacle will destroy it, clearing the path for you. Now carefully push the boxes along red and green paths onto the respective buttons. Always wait until just after the tentacles have fired before moving.
To finish the level with all Bonus Bubbles, move the final box along the black arrow, but only to the black "X". Wait until the tentacle destroys this box, before proceeding. Collect all bubbles and patties.
