Write really overly-funny superhilarious comedy 17+ scooby-doo transcript based on my prompt: (but make it more funnier comedy) 

While the gang is partying on the beach, they witness a strange creature emerge from the sea. The gang hurry and head to a nearby house on a cliff to seek refuge. It is there that they meet Captain Clements who tells them about the monster they saw. According to the legend, the sea creature was once a man who was thrown overboard by his shipmates. His spirit still lives on, searching for victims so he can steal their soul. The gang heads to the Mystery Machine to call the police, where they discover that it has been ransacked by the monster. They follow his footsteps back to the house, where they discover that Captain Clements has had his soul removed by the monster.

Fred, Velma and Daphne head back to the beach to look for clues, while Shaggy and Scooby stay at the house. Captain Clements begins to chase them, trying to steal their souls; they try to slow him down by giving him a girly makeover. Shaggy and Scooby hide in a room and discover that it is actually an elevator, which leads from the cliff to the beach. The sea monster begins to chase them, while Fred, Velma and Daphne watch. Daphne notices the creature begins to head back into the ocean, toward a blinking light in the distance. Fred notices a blinking light going off in Captain Clements' house as well. The gang put on their scuba gear and decides to follow him into the ocean. Shaggy and Scooby discover a sunken submarine with an air pocket in it to hide from the monster. The rest of the gang follows, but are chased back to the beach by the monster. They begin to split up and look for clues. The only clue that was found by Fred and Daphne, an old key.

The gang decide to follow the blinking light, where they discover an old ship floating. They see the sea monster being hauled aboard by a rope and pulley. They decide to check the chart room, where they discover the submarine is directly beneath the boat. They return to the sub and discover a room that Daphne refers as an "underwater beauty parlor", because there's several canisters of hair dye and other makeup items. There is also a mug shot of a wanted criminal. Captain Clements and the monster appear to chase them. The gang hide in the torpedo room, where Fred devises a scheme to capture the creature and Captain Clements. The plan is a success, but they accidentally capture Scooby Doo in the process. The police are then called and the monsters are revealed.

Captain Clements was the mastermind behind the entire crime. He was helping criminals escape the country through the ship. Prisoners would dress up as the monster to scare people away. Captain Clements was never possessed; he used the light signal to let prisoners know when he was ready to ship them. The sea creature costume had a jet motor in it, enabling the criminal to quickly swim out to the sub, were Captain Clements would be waiting to change the criminals appearance and give them false identification papers, then the criminals would be taken out of the country on the ship. The monster is revealed to by a notorious bank robber who just broke out of jail, with the homemade cell block key Fred found.

The sheriff asks how the gang were so brave with Shaggy replying they're not scared by big monsters. Just then, Shaggy and Scooby are scared by a small angry crab which chases them across the beach as Fred, Daphne and Velma watch in amusement.
