The t-rex's jaws could crush the bones of a multi-ton Triceratops. It could sheer flesh from the hide of the largest game in its natural habitat. But the inside of its mouth was full of clusters of nerves and sensitive.

There was really only one proper response to what this tiny monster was doing, and that was to spit her out. Which she did by regurgitating a mass of spit and various things she'd eaten and thereby force her out.

This would be very disgusting.
