Sans: "Amalgamates...?  I don't remember any of those."
Papyrus: "..what even ARE amalgamates?"

*Frisk shivers*

Frisk: "...you don't wanna know."
Anti: "I'm confused now."

A/N: Keep in mind, the amalgamates were accidentally created by Alphys, who is young in this background/story.  They don't really take any role in this...yet.  Sorry.
