Joy is teaching Hyrum a new song. He enjoys acting it out. The song? "The bear went over the mountain." She introduced the concept of a chair being the mountain, and that was it. Now he grabs his big blue bear from his Grandma Joy and bounces him up and down on top of the 'mountain' with glee. At some point, he throws the bear over the mountain to celebrate the bear's crossing.
Joy explains, "And then he runs down off the mountain, grabs the bear, and says 'Help. Help' which means 'Wait. Wait. Don't start singing again until I get back on the mountain."
