Push the boxes along indicated arrows (be careful to move box 5 only one step). Now, in order, move boxes 1-5 to the indicated matching positions. The blue button should now be pressed. Push the beachballs, one by one, to build a bridge and activate the green button. Return to the purple button to free the Jellyfish.
Jellyfish will collect any Krabby Patties for you that they encounter (however, they do not collect Bonus Bubbles). Let the Jellyfish collect the patties, and push the red button, then collect the remaining Krabby Patties yourself.
