During the historic pandemic of 2020, the members of 3 Leg Torso were recruited by a large, mysterious man to travel to Frostländ and become elves in his toy workshop, which actually turned out to be a small cabin in the woods with no heat, frozen water pipes, and a tiny room full of tools which quickly became obsolete for making toys...because they were frozen solid to the benches!
 
Steadily, the newly appointed elves survived the chilling darkness and crippling mental depression by playing  their various musical instruments they were allowed to bring on their journey, and with this, they discovered that their music somehow magically heated their icy cabin.
 
Towards the end of the toy-building season, the Elves happily wrapped up their duties at the workshop, ready to depart for home, but just as they were leaving, a freak ice storm stranded them for another season. As they experience yet another wave of dread and hopelessness during this period of frozen isolation, random visitors arrive at the cabin, bringing supplies and spreading  joy - and much of this joy is spread through the sharing of music.
