"Something is missing"

In 2022, I self published my first children's book (1-3 years old) named "Something is missing". Written and illustrated by me, "Something is missing" is about a little kid called Robbie, who lost a sock after taking a nap. After looking for his sock for a while, Robbie decided to ask Lilly for help. Lilly is a cute little dog who seems to be playing more than helping Robbie. However, Lily finds the sock! Where do you think it was?
