Mr.Smart found a small pink umbrella on the ground. When he was happy, the little rabbit came over and wanted to join him. The little fox, the little pig, the little hippo, and the little elephant all asked to join in. Just when everyone was happy to cross the bridge with the umbrella, a small frog jumped out suddenly and everyone fell off the bridge. Fortunately, the beautiful umbrella like a small boat carried everyone downstream. Finally, when docked, the umbrella got back to its real owner.
