Better Late Than Never

Alyssa was pretending the bathtub was her stage and was practicing her "Jingle Jam" song before school.

If you can't tell she is singing "I Want a Hippopotumus for Christmas"
Of course Micah didn't want to be left out. So, once Alyssa hopped down from the tub, Micah jumped up and started singing too.

I'm not sure, but I think Micah is trying to sing Jingle Bells.
