Enchant creature you control Enchanted creature doesn't untap during your untap step if Cocoon has a pupa counter on it. When Cocoon enters the battlefield, tap enchanted creature and put three pupa counters on Cocoon. At the beginning of your upkeep, remove a pupa counter from Cocoon. If you can't, sacrifice it, put a +1/+1 counter on enchanted creature, and that creature gains flying. (This effect lasts indefinitely.)
