If you call Papyrus while you are in Mettaton's old house in Waterfall (next to Napstablook's), Papyrus will say that the house belongs to "Happstablook, the Happy Ghost". Additionally, the name of that room in the files is "room_water_hapstablook"
Just a note: The only name given to Flowey's final form is "Photoshop Flowey". It has never been referred to as "Omega Flowey" in any official context. That is purely a fanmade name.
