We have a big Bur Oak tree that is in front of our porch. Roo Roo loves bringing the big acorns and crunking them up and leaving remnants on the couches, bed, and floor. You should hear the noise that my Human makes when she accidentally steps on one. It's most effective when it's in the night and she can't see them!
Besides being fun to have humans step on, they make a really loud noise when they land on the roof.
