Gigglys are the second most common sentient animal on Mars, after Martians, of which they are related to, and throughout their history they have done a lot of land reclamation. They have skin like humans do, but otherwise look very difference. They have two and a half heads and swim like jellyfish do (gigglys are semi-aqautic). They have skulls in their heads but no bones anywhere else in their bodies, although they do have hooves. They are in three colours which are red, black and orange. A widely spoken language created by gigglys is phungian.
