Sidequest: Raise a Chocobo

The back face of a nonmodal double-faced card usually has a color indicator that defines its color.

If you are instructed to put a card that isn't a double-faced card onto the battlefield transformed, it will not enter at all. In that case, it stays in the zone it was previously in. For example, if a single-faced card is a copy of Crystal Fragments, it will be exiled during the resolution of its second ability and remain in exile.

Sidequest: Raise a Chocobo's last ability checks at the moment it would trigger to see if you control four or more Birds. If you don't, the ability won't trigger at all. If it does trigger, the ability will check again as it tries to resolve. If you don't control four or more Birds at that time, the ability won't resolve and none of its effects will happen.
