Rumbly?

Jackson watched Winnie-the-Pooh on Monday and walked around all day looking for his "rumbly". Apparently in the episode Pooh lost his "rumbly in my tummy" and after watching Jackson spontaneously cup his hands around his mouth and yell "Rummy?! Rummy?!?" several times it finally dawned on me. I even saw him check under the couch several times. What a laugh I had about that!
