Alright, it is something new: Papyrus frequents the True Lab... to use the shower.

First, I thought that there are bathrooms in the underworld. But it turned out to be highly questionable. Papyrus excuses himself by saying to go there, but there is an other monster, who looks forward to trying bathrooms. Also, Papyrus admits he doesn't know what a toilet is, right after asking if you are using it. Still, after all the crazy and illogical stuff, we are left with four things that, combined, may make sense:

1.: Sans mentions that Papyrus cleans his battle body by having shower, 2.: The only known shower in the entire game is in the True Lab, 3.: Sans is speculated to have access to the True Lab, so he may be able to let Papyrus in, and 4.: Papyrus is crazy/naive enought to just go in there, and walk past the amalgamates without realizing what is going on around him. Probably even waiting for his turn, as we know something tends to be in the shower.
