What are your favorite outdoor props for kid portraits?

So I've been taking lots of pics of our 2 girls lately and I've seen some interesting props on some photos here that sparked my interest in stepping it up to something like them, but I don't want them to look too composed or cheesy. Saw some cliche red wagon pics that looked great, and I've got an idea for chin resting on crossed arms at a table that I may try later this week once the girls aren't sick.

Anyway, looking for some other ideas that we could either shoot with in the back yard, or carry off to the park with us. Pics would be great too!
