Don't Eat the Ice Cream Man

A few weeks ago I was playing with the girls. They were fairies and I was the mean monster trying to catch and eat them (or force them to clean, a fate much worse than being eaten). After a while Adriana decided that she wanted to teach me to be a nice monster. These are the rules she came up with:
In case you can't decipher kindergarten sound spelling, that says
1. Learn to be nice.
2. Be nice to others.
3. Be nice to everyone.
4. Don't eat others.

#5 was my favorite.

"Don't eat the ice cream man." I have no idea where that came from. We didn't have an ice cream man in our game and we hadn't been talking about an ice cream man at all. Apparently that's an important rule for every monster to know. I did not eat any ice cream men, and I was able to "pass off" all of my rules to the girls' satisfaction (with only a few unauthorized nibbles of toes and fingers).
