After the children had asked for several days
Yes, in fact, I was a troll and a witch again yesterday, so little is needed to frighten a child with joy. Saw someone calling for green teeth.
I use lip balm and green eye shadow on my lips and ugly rubber teeth and luckily they are so used to me dressing up once in a while now that they like to sit on my lap and pull my witches nose a little and laugh.
