About Gleep and Gloop[]
Gleep and Gloop are two protoplasmic creatures. They are able to absorb and deflect energy blasts and laser beams, often placing themselves between attackers and other Herculoids to act as shields. They can also form shapes including, but not limited to: cushions, trampolines or parachutes to break falls; stretching themselves between tree limbs or rocks to act as slingshots; encircling an attacker's limbs to restrain them, or the entire body to squeeze and render them unconscious. Gloop is the larger of the two.
