Main walkthrough
- Pick up clams on the beach. Face the lighthouse keeper and hold Q to sell them for $1 each. You can also eat a clam if you need to restore hunger.
Pick up clams on the beach to earn your first money - Buy the Crab Fishing Rod for $3. Catch and sell crabs, shrimp, and other creatures until you can buy beer for $12 and a knife for $45.

Install the empty can on the Crab Fishing Rod - Cast the rod to hook the Spider Crab. Move aside when it charges, then attack its back while it is stunned. Try to keep it away from the water because contact with water allows it to jump much higher.
Move aside when the Spider Crab charges 
Pick up the shell separately after defeating the Spider Crab - After the fight, pick up the shell rather than a meat chunk and give it to the lighthouse keeper. Take the boat keys, buy the $10 radar, press Q to place the radar on the boat, and press E at the controls to start driving.
