The Tingle Tangler was a plant lifeform that originated from Cetus Beta in the Gamma Quadrant. It resembled a ball made of grass or rope.
Its one of the attack plants that exists on its world, when another plant gets close it explodes shooting out ropes like a net which it uses to wraps up its victim and then gives it a powerful electrical shock. This stuns the plant long enough for the Tingle Tangler to eat it.
After his adventure on Cetus Beta, Nog gave the stasis pouch containing the Tingle Tangler to his uncle who unfortunately was not told of the plant's unique characteristics. (DS9 novel: Field Trip)
