Reanimated Surface Skeleton Will Play the Seasonal Boss Music

Summon a reanimated skeleton on the surface in any season.

Hit it a bit to start the combat music. 

What you'll notice is that the music that is being played is the music of the seasonal boss.

This is similar to the bug report where Malbatross would do the same thing at one point, and has been since fixed.

I don't know what music is supposed to be playing for the skeleton though.
