In an abrupt storm on the ocean you are alone with a boat, you try to keep the rudder steady as much as possible, but the boat seems to go where it wanted to go. One part of the mast, where the sails were closed, all of a sudden you are hit by a log and it was dark. The next day you wake up inside a mysterious creature that is said to be "everything can go in, but nothing can come out" according to this logic you are inside Monstro.
