Tentacle is a type of monster or creature often found in Japanese anime and manga. It typically consists of a long, flexible body with multiple appendages called tentacles. These tentacles are often used to capture, constrict, and/or restrain victims. In some works, tentacles are used for a sexual purpose, and in others they are portrayed as a threat or a form of punishment. Tentacles are also featured in some live-action films and video games.
