Lily is a little girl with big emotions. And sometimes she can't keep herself from acting out and being naughty. Or rather, her imaginary friend, Tiger, is the naughty one. So when Tiger convinces her to run away, they have a blast stomping and jumping and going wild. But what is Lily to do when their adventure starts to feel a bit too wild?

Tiger Wild gently illustrates how sometimes we all need a little help when certain feelings are hard to express. For there is a time to be wild and a time to be mild.
