Letting a bladed enemy into her mouth seemed like a stupid idea, to anyone that hadn't had experience in the subject at least. Having been unwillingly attacked in the mouth before, Garudamon had realized that the inside of her beak had more of a defense then she thought. Enduring the agony her mouth was experiencing, the bird used her tongue to slam Matadormon against the roof of her beak. The roof of her beak being as hard as the outside, it would be the equivalent of being slammed against stone.
