Even though some of these crossovers are not completely mine,I changed up some of their designs a little (don't get mad)

OH WOWIE!Pen as Papyrus.I think this is awesome since Pen is my favorite male character in BFDI and Papy is my favorite male character in Undertale.

Eraser as sans.Pretty cool.I believe they have something in common that makes this awesome!

Leafy as TorieI.I really changed her up from her original design by someone else (you know who you are) I think this was a good idea,because of how extremely nice and protective they both are.

Teardrop as Napstablook I changed this alot from the original design too.I redesigned him so he could look more like the one in Undertale.

Flower as Flowey.I guess this was obvious.

Pencil as Undyne.I really redesigned her alot(I'm sorry,but I don't like her original design)I believe Pence-Pence was picked to be Undyne because she was the closest object that could become a tomboy,I guess.

Firey as Grillby.This was obvious as well.Because they're both fire.
