The first variant, known as a "Drag Tentacle", usually tends to attack Isaac by launching out of a hole that it has made in an area, and grabbing a hold of him. It is unknown how they produce these sounds as they do not possess any visible mouths or anything else that could produce any animal-like roars. They can also be heard emitting loud and high pitched screeching noises. Tentacles emit loud elephant-like roars when they are far away or when they appear out of nowhere as a scare-factor. The purpose of this liquid filled sack is unknown. This area is not as heavily armored as the rest of a Tentacle and thus is susceptible to damage if a weapon is fired at it. This spot connects the "stem" and "tip" areas of a Tentacle. Located in between the "tip" and "stem" area, a large sack filled with yellow glowing liquid can be seen. This area is heavily armored and resistant to damage from any weapons that Isaac may use against it. They appear to be formed from muscle tissue, internal organs and possibly bone.


Tentacles are either stationary Necromorphs that belong to no other creature or they are part of a bigger Necromorph.
