During his battle, when the dog steals his attack:
Then when the dog “helps” Paps out during then normal attack:
Then afterwards on the date/hangout, when the dog gets into Papyrus’ bones again:
On the abandoned genocide route, when the dog makes off with Paps Special Attack, and then Paps expands a bit on his interactions with the dog on the hangout.
Namely; that it sleeps in his bed with him (cute):
Poff zone phonecall:
Papyrus: THE STATION OF GREATERDOG. HE LOOKS A BIT LIKE A CERTAIN DOG I DON’T LIKE. BUT GREATERDOG DOESN’T COLLECT ANYTHING. HE’S ONLY A KLEPTOMANIAC FOR AFFECTION!
The Dogroom:
Where Papyrus can sense the dogs existence in the room (the dogs, ah, residue. If I may phase it as such). And while he calls it annoying, he also voices affection. Similar to him letting it sleep in his bed.
Papyrus: HMMM… THERE’S SOMETHING ANNOYING ABOUT THIS ROOM.
Papyrus: BUT I CAN’T QUITE PLACE MY FINGER ON IT… THEN MY PLACE MY WHOLE HAND ON IT… THEN PET IT AFFECTIONATELY
Elevator l2 in Hotland:
Where he expands once more on things the dog takes without asking. First his bones, then his lasagna! But he also then gives the cute image of the dog sleeping (in a Garfield reference).
Papyrus: THE ELEVATOR SAYS L2. BUT WHAT DOES THE L STAND FOR? LASAGNA? I HOPE NOT. I DON’T MAKE LASAGNA ANYMORE. THAT GLUTTONOUS DOG ALWAYS EATS IT FIRST! FIRST MY BONES, AND NOW THIS
Papyrus: THEN IT RETREATS INTO A SHALLOW BLUE BOX. COVERS ITSELF WITH A BLANKET, AND SLEEPS
Around the Hotel, with Undyne:
Papyrus: CAREFUL. I’VE HEARD THAT HOTEL HAS A DOG PROBLEM.
Undyne: Oh? No pets allowed, huh?
Papyrus: I’M NOT TALKING ABOUT PETS.
Undyne: What’s the problem?
Papyrus: THE PROBLEM IS… DOG.
Undyne: What’s wrong with dogs!?
Papyrus: NOT ALL DOGS. JUST THAT ONE.
Undyne: What’s WRONG with it!?
Papyrus: EVERYTHING.
Conclusion: Anomalous characters just really like Papyrus… Flowey, Frisk, Sans, the Dog…
Other reality breakers all treat Papyrus as unique, and the arguable “god” of Undertale itself spends the majority of its time with him and getting Papyrus to focus on it.
I just kinda think that’s important to note tbh.
[Is it completely understandable to compare the Annoying Dog’s relationship to Papyrus as a TV sitcom friendship?]
I think it’s adorable how Annoying Dog/Toby Fox has such a fascination for Papyrus, but yet expresses that fascination by continously stalking and irritating him. There’s just something hilarious but cute about it.
honestly just really like undertale
