Ralas

The Ralas are a race of frogmen from a hidden second satellite of Earth.

Biology
The Ralas have green mottled skin and stand seven to eight feel tall. They walk on bowed, powerful legs and have arms that end in webbed paws. Their heads are bulbous in that they are wide, with unwinking frog-eyes that sit on the sides. Their mouths are white-lipped and white-lined. They also diet on green man blood.

Culture and society
The Ralas are an advanced culture, possessing anti-gravity boats that are also amphibious. They have weapons that are black metal tubes, similar to pistols that can cause objects to vanish. They constructed an enclosed city that could only be accessed via underwater passages within the sea that surrounded it.
