Sucking Cups

We get several tree frogs each night on our sliding glass door. Isaiah usually points them out and counts them. Well tonight he was over looking at them and says, "Mom, you see the frogs' sucking cups?" I had him repeat it several times and I even had him go into room and tell Matt. We seriously can't stop laughing! This kid is just too much!

We're pretty sure he's referring to the bottom of thier legs, they look like suction cups. Oh and we have no idea where he learned anything about suction cups!
