Cannonball Run
Avoid the first tentacles' fire and push the steel box into position along the yellow path. Wait for tentacle fire to pass and push the box one step left, and then up the corridor by moving along the white path. Wait for the tentacle marked in purple to fire before moving along the purple path. Wait at the path's end for all Frogfish to be eliminated.
Use the two steel boxes to build a bridge across the water and lure the Frogfish onto the yellow button (along the red path). Collect the bonus bubbles and press the green button. Finally move the third steel box (marked in blue) along the blue path to safely reach the Krabby Patties.
