They somehow keep finding a way in the human world. Which lead you to having to keep them in your house, one day you were out shopping and everyone just wanted to come with you. You agreed but Wally, Julie, and Sally had to sit in the cart since they were the smallest and childish, you pushed the cart down the aisles as all 8 of them ask for something. You asked them what they wanted and they replied saying...

Julie: "Rainbow cake batter!"

Sally: "Cookies!"

Wally: "I wanna go home"
