Molly, Grandpa, Dad and Tooey go on a snowmobile adventure to search for hot springs in the backwoods.
Molly sings little diddy while dance-shuffling. The closed captions include musical notes around her words as she sings it:
hidden hot springs, but not for long
it's geothermal phenomenon
ha, ha, ha, I dip my toe in
ha, ha, it's really hot
The latter lines do not represent laughter, but rather gasping at exposure to temperature extremes.
