why do some dog residues sell at different prices at the tem shop?

(undertale spoilers)

While it may seem like Dog Residue is Dog Residue no matter how one looks at it, this isn’t the case in the code. In terms of game mechanics, Dog Residue is handled as six separate items, each with not only their own separate flavor text, but also separate sell value.

This means that whenever the game fills out your inventory upon using Dog Residue, it actually picks from a pool of seven items (Dog Salad and the six types of Residue), rather than just two. This is why not all Dog Residue are sold at the same price.

Note: The Dog Residues are in the same order as in the previous screenshot.
