Instructions
Leave the main school building and travel to the right, past the signs that read ̶0;Climbing Wall̶1; and ̶0;Puffin Point,̶1; until you reach a lighthouse.
Climb onto the pier below the lighthouse and talk to the man on the docks. He will mention that a lobster trap is underwater.
Equip your scuba gear from your list of items. Jump off the pier and select the ̶0;dive̶1; option that appears on-screen.
Swim downward until you locate and collect the lobster trap. Afterward, you will run out of oxygen and return to the surface.
Talk to the man on the docks to return his lobster trap. He will give you a lobster and keys to a jet ski as a reward.
Walk to the left and climb the ladder to the top of the lighthouse.
Stand next to the spotlight fixture and select the lobster from your inventory. The light will rotate and shine toward the school, scaring the bird away.
