Lambert didn't actually know what it was called, so he pauses a little. He's only ever thought of it as 'the wiggly thing you hit people with.'

"Not just any 'pool noodle.'" Lambert wiggles it at her menacingly. "It's magic. Not enough to kill something, but enough to stun, if you swing it hard enough."

And more importantly, it's at least reasonably feasible for a tiny girl with one broken arm to hold onto. To demonstrate, he lets the noodle's tip wiggle towards her. Very, very lightly, unless she moves out of the way, he touches it to her forehead.

It'll feel a bit like someone just took a finger and flicked it very hard against her head.
