Is she STUCK, or just being a little turd and refusing to come out?
If you continue to try coaxing her out, she may just come out on her own. However, I would be worried that she gets in deeper and gets stuck, or even chews her way up there. I would say try to make the hole larger- it was there anyways, right? Maybe no one will notice.
Just continue offering different foods, maybe not something she can grab. Try mashed up fruit or yogurt on a spoon. Let her lick some off wherever she is, and then pull it away slowly until you can grab her by the chest or scruff. Just be gentle....
