Remix this game and make a custom skin for your entity i might even add it to the game ;)
Eyespore bursts into eye mushrooms, eye mushrooms shine lights that heal you and slow you down, both increase the longer you are in it, but once you are in the light for too long, it damages you. Eyespores feed on the nutrients and energy of dead humans, they need the nutrients to make mushrooms but often get too much of it, the light they emit is actually spores, they have healing properties but can get very deadly if you're in it for too long
