As Bonnie creates Forky, to the right of her head is a girl with jet black hair and a pink shirt who bears a striking resemblance to Boo from Monsters, Inc.

Whether you wrack your brain trying to figure out the mechanics of these two characters co-existing at this age or just accept it as a cute reference, it's a neat inclusion.
