In fact, aliens can visit our planet incognito, without attracting attention, masquerading as exotic animals or even plants. In the game Green Monster Kids Rescue, you will help a green alien who arrived on the planet long ago, settled in a remote forest hut and even had children. Every day the parent left home, exploring the planet, collecting information and getting food, while the children stayed at home. They are tired of being locked up, they ask you to open the door for them to Green Monster Kids Rescue.
