'Squeaking' is a terrible word and cannot possibly apply to any action undertaken by someone as magnificent as Peter. If he could remember the right word for it, maybe it wouldn't be quite as bad.

He does squeak at the boulder, though -- and then a second and third time as they leave it behind. Carefully turning around on his twig, he squeaks at Daine's legs as well, but that proves to be too much and he falls silent.
