 SCP-365 is a green pool noodle made of polyethylene foam. By itself, it displays no unusual properties and is physically identical to a typical noodle of similar size. SCP-365's unusual properties manifest only when it is placed in a body of water. When a subject completely submerges in said body of water, they become unable to get out. Scientists report a sense of dread and describe themselves in an infinite sea, swimming endlessly in a direction and finding only more water. It is important to note that to outside observers, the subject simply seems to be flailing in place. The only way to remove a submerged person from the water is to remove SCP-365.
