Shaymins form changing, can it be reversed?

Question

Once you have changed shaymin into its sky forme can you change it bac

Answer 1

When you give it the Gracidea, it will turn into Sky Forme.
Then, if either:
- Shaymin is frozen. (FRZ)
- It is nighttime
- Shaymin is not holding the Gracidea
Then it will turn back into Land Forme.

Hope I helped. :)
