It was great to visit you last night, (child’s name)!
I got the chance to bring my magical horse with me on this journey around the world. My horse (can insert a name for the horse if you like) loves to visit good (girls/boys) like you!
Enjoy your special treat and I’ll be sure to visit again when you lose another tooth.
