When this Aura enters, tap enchanted creature and put three pupa counters on this Aura.
Enchanted creature doesn't untap during your untap step if this Aura has a pupa counter on it.
At the beginning of your upkeep, remove a pupa counter from this Aura. If you can't, sacrifice it, put a +1/+1 counter on enchanted creature, and that creature gains flying.
