Constrict (Ex): On a successful grapple check, a juvenile grell deals 1d4-1 points of damage.

Improved Grab (Ex): To use this ability, a grell must hit an opponent of its size or smaller with a tentacle attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and can constrict.

Paralysis (Ex): Any creature hit by a juvenile grell's tentacle must make a DC 7 Fortitude save or be paralyzed for 1d4+1 rounds. Each additional tentacle that hits the same creature that round increases the save DC by 1.

Sightless (Ex): A juvenile grell is immune to gaze attacks, visual effects, illusions, and other attack forms that rely on sight.
