At least at some point the singing cuts out to be replaced by entertained laughter.

Twirling is abandoned for lithely veering around the creepy Kram-mobile and then they're at the door, right in front of Maggy, seeming to almost vibrate with poorly contained glee slightly too far into his personal space.

"Hey."
Not suave or echoing or mysterious at all.
More of a fragile, apprehensive whisper sort of thing.
