Jay startled a bit at Boo offering a greeting. He flailed slightly pushing the top of the backpack to an upright position. He got a low grunt of annoyance from inside the backpack for his efforts.

Then his attention was torn away from Boo to the puppet. Which was making a noise remeniscent to something that happened in a horror movie when an ax murderer popped out.

Jay looked at the puppet. Then at Alexis Alex Lex. Back to the puppet. Back to her to try to figure out how the hell she made that noise.
