Trundle Santa
Trundle needs a Christmas skin. Old Saint Trundle. Wears a santa suit ,with a big candycane for a weapon, and a bag of presents on his back. His Q and R abilities would be the same but his W and E abilities would change. W-Frozen Domain= Icey floor with candycane border E-Pillar of Ice= a Christmas tree with presents under it, OR a big pile of stacked up xmas presents.
if his R HAD to have something R-Subjugate= While active the target would have bells floating around him/her(they dont hurt the person or do anything special just there for show) and Trundle would do the Ho ho ho thing.
