It is a disagreement.
Vampy dislikes Halloween because it is too commercialized and doesn't focus on praise for Satan, or as Vampy calls him sometimes, our father below.
Mr. Pumpkin, on the other hand is quite fond of Halloween as it increases pumpkin sales, use of pumpkin seeds, pumpkin spiced latte, etc.
He even insists that our lighted pumpkin be pointed to the street to publicize the miracle of pumpkins.
