She will cover up her eyes with her hands to start playing. She might crawl behind a piece of furniture and then pop out. She might even crawl right up to you, squat down and then pop up at you.
But this one is a new favorite. She will put a bucket on her head and wait for you to say, "Where's Lily?!" before taking it off. She thinks it's hilarious if you go touch her before she takes the bucket off her head too.
