Tentacle is one of a number of ghosts that appear in the Subway at 21st Street in the Extreme Ghostbusters Intro. It has also appeared in episode "The Pied Piper of Manhattan" in the first scene and later in the city as one of ghosts causing havoc before Piper shows up.
It appears to be floating intestines with eyes on the ends. It could also be modeled after staghorn coral.

- Because the Disney re-airings of the series are the most commonly watched, the ghost is not noticed by viewers as the logo blocks him from most viewing in the subway part of the intro.
