Santa’s sleigh must be taken to one of four special sleigh workshops for inspections.
One of these workshops is specially designed to keep the sleigh stable – but Santa has a small problem: he has completely forgotten which one is the right one.
This is not insignificant, because his sleigh must be perfectly level during inspection. Even the slightest tilt or sudden movement could cause damage to the sleigh during inspection.
That’s why Santa needs a workshop where his sleigh can remain stable, steady, and without any sudden movements until everything is complete and he can begin his journey around the world.
