Martian Egg Monster

The Egg Monsters from Mars were a group of oviparous, amorphous extraterrestrials originating from Mars. They are described as resembling a pile of rotten scrambled eggs with eyes. Despite their appearance, they are benevolent creatures. The eggs arrived on Earth during a meteor shower that only hit the protagonist's town.

Behavior
The egg Martians can tolerate arctic temperates and appear to "melt" when their environment becomes too hot. This is presumably due to their having evolved in the frigid environment of Mars.

Reproduction
The first batch of egg monsters hatched from enormous black–and–green eggs that fell from the sky into the protagonist's neighborhood. However, after the protagonist spends a night sleeping covered from neck to toe with a blanket of egg monsters, the next morning he laid "the biggest egg you ever saw". It is unknown whether this egg, if it should hatch, would have produced a human–Martian hybrid or not.
