(Toby Fox owns UnderTale, I plan to replace the cover with my own, and there needs to be more Sansgore like what the actual heck) After the surface was finally in the monsters grasps, they were so excited to move on and find new lives under the sun.

Asgore agrees. They're totally not gay for each other.
