LOL... The frosting thief... Was definitely Onyxx.
See.. She'd take the decorating tubes - the colored stuff - and eat them.
So one Halloween, I'm getting stuff together so she & Jett can go to Grandma's and do cookies. But I can't find the icing! So I go hunting. I can't find it. I'm ready to go, but can't find the kids. So I go into Onyxx's room for something else... And there is an icing tube poking out from under her mattress... All three, Orange, Black and Green are there. I grabbed them, put them in the bag, and we went.
Got to Mom's house, handed Onyxx the bag and told her, you decorate with these, Jett can use the other stuff.
You should have seen the look on her face when she opened the bag...
The next time my purple icing was tasted, it got put back in the cabinet... But the huge purple smear on her neck kind of gave it away... I laughed at her.
