# Breeding and Grow

There are 2 stages of evolution on the planet Monster Arena, the Egg Stage and the Adult Stage. Only adult MONS can participate in other activities such as Farming or Fighting Monsters.

The player can buy eggs from MarketPlace and then incubate them to hatch an adult MONS. Both buying and hatching eggs need to use MON tokens.
