Made mostly as a joke in about 2 whole days (i binge work i guess) this mod simply adds sans the skeleton from Undertale as a boss that can spawn in some cold biomes
(Sometimes when hit he's got A special little surprise he'll spawn in for you, pro tip, they can't be killed by normal means per say)
This mod doesn't add any new items as of now, it might eventually if i ever update it
There is also a command to easily summon sans if cheats are enabled. (/pun)
