While the giant is still disabled, you run out into the snow and head for the semi-circular building. You glance back one last time at the giant and sigh. Sorry…

Upon arrival, you find what appears to be 4 or 5 sets of tracks in the snow heading north-east. That electrical thing must have followed them! You race after the tracks, but find they reduce to only a clear 3 after about halfway. That would mean the electric shadow gave up and went back to the semi-circular building. You continue onward, following the tracks toward the building with the high roof.

Puzzle complete!

After reaching the building you find it to be much larger than any of the others. It’s base alone stands taller than the long building to the south of you. The roof only adds even more height.

The 3 tracks lead right up to the doorway, so your friends must be inside.
