One-Eyed Willy was a famous pirate back in 1632 and he got trapped in a cave in Astoria, Oregon. Mikey, Chunk, Mouth, Brand, Stef, Andy and Data went to find his "rich stuff". Chester Copperpot was the last person to search for One-Eyed Willy's stolen treasure. The Goonies found his treasure aboard his ship and then the Fratellis came in and set off a booby trap that freed Willy's ship, The Inferno, from the cave. The Goonies tried to get a cave wall to open so they had to use their final dynamite/candle to blow a hole in the wall which failed and caused a giant boulder to fall over the hole blocking their way out. Luckily, Sloth was strong enough to lift the boulder. Unfortunately for Chunk, who thought of Sloth as a brother, Sloth couldn't make it and the giant boulder fell behind them, which for-longed Chunk. They then got out and they saw The Inferno sailing at sea. It is not known where Willy and his ship went.
Not much is known about One-Eyed Willy's background story, other than he was literally born with only one eye, and that he became the most famous pirate among pirates in his day, possibly the most dangerous cutthroat to ever sail the seven seas. Willy is known for his creation and use of ingenious traps that could take down even the most experienced treasure hunters. One day, Willy and his crew stole a great treasure of gold and jewelry, then they loaded it all up onto his ship, The Inferno and they sailed away into the sunset. Then when word got the British king about the theft, he sent out an entire armada to go after the pirates. Then after a few weeks, they finally found Willy. Then there was a big war between the armada and The Inferno, during the fire fight, there were guns bursting, and cannons blasting, it was massive. Then Willy fled because he knew he'd get killed if he stayed around, and then he and his men got into a cave, and the British blew up the walls all around him. Caving him in. Ever since then, Willy had been there, forever trapped. For 5-6 years, One-Eyed Willy and his pirates had been down there digging tunnels and caves, and setting booby traps so that anybody who tried to get in would die. Then once their job was done, Willy killed all his men so that they wouldn't get to his treasure. Although, it is said that one of the pirates must have gotten out alive, with a map and a key.
