Growmon Island is a creature-collection idle sandbox that lives in a small area of your desktop so you can multitask while your Growmons grow. Each Growmon progresses through four growth stages - Egg, Baby, Teen, Adult - and every stage can branch into multiple evolution paths.
You can sell Growmon once it hatches for coin, or keep it to gain passive boosts. Train Growmons to increase their quality — higher quality raises sale value and influences evolution outcomes.
