Santa's Secret

We continue to be amazed by Old Delft.
Two years ago, while constructing the Seasonal Room, we unexpectedly discovered a passageway to Santa's workshop. Now, we have found a hidden door to Santa's house in the back of the basement.

We encountered a Christmas elf in a state of panic.
It turns out that Santa is ill, and the reindeer no longer have the energy to pull the sleigh.
Of course, we immediately promised to help, but unfortunately, we cannot do this alone.
However, Santa Claus does not want his secrets to be revealed and has forbidden us from helping.
Fortunately, Santa Claus takes several naps every day, so we can keep our promise to the Christmas elf. After all, a promise is a promise.
Will you help us keep that promise?
