Underswap

Underswap is an AU created by popcornpr1nce. The AU "swaps" related characters with each other (for example, Papyrus is swapped with Sans).

Underswap used to be posted on popcornpr1nce's personal blog, before popcornpr1nce and created a blog for Underswap at the address "underswapped.tumblr.com" (not underswap.tumblr.com, since that address was already taken ) along with his friend @coastrobbo (referred to as "Robbo" on the blog).
