The squeaks somehow seemed to shift from shock to being indignant, as if he was chastising Thrawn for even suggesting that the change had been voluntary. Of course it hadn't been. It wasn't like they'd hit a certain altitude and he'd decided that he needed to stretch his wings.

Even though he was squeaking and chirping incessantly, he did obediently climb onto Thrawn's hand though- heading straight for the opening in his sleeve. The bat form was convenient both for hunting and for fleeing, but being forced into a form that was not his own had still come as something of a shock.

Not quite the same as involuntarily becoming a monster, but still not comfortable.

And worse, it wasn't just him and Thrawn as witnesses to this embarrassment either.
