Tentacles

Tentacles are parasitic beings from another dimension, typically summoned for lewd acts.

Anatomy
Your typical Tentacle is about 3 feet long, and 4-6 inches wide at the base. the end of a Tentacle contains an orifice designed for laying it's eggs. A Tentacle typically survives by soaking up the nutrients in it's environment.

Life Cycle
A Tentacle begins it's life in a egg, approximately a one inch diameter sphere surrounded by a thick, almost mucus like substance, that is deposited into a suitable part of a host organism for it to incubate. within 3-5 hours, the Tentacles within the egg will have matured enough to hatch, and will usually do within the host itself. once the host has given birth to the ~5-10 tentacles that hatched from the egg, it will usually take the Tentacles 24 hours to reach maturity. during this time, the tentacles are mostly harmless. A mature tentacle is capable of asexual reproduction, but requires a host to lay the eggs, and will seek one aggressively.

Summoning Tentacles
Most magicians and mages capable of using magic have the potential to summon Tentacles from their home plane. Doing so will root the Tentacles to a chosen part of the summoner's body and give them complete control over the Tentacles. These Tentacles can be banished at will, but all residue (mucus, cut off bits, eggs) will be left behind.

Tentacle Mothers
Under certain circumstances, it is possible for all the tentacles from one egg to recombine into another being known as a Tentacle mother. these are smarter than a normal Tentacle and often care for newborn Tentacles within there vicinity. other than this, not much is known about them.
