So? Toby was planning to make something like Deltarune originally. Then he set the project aside and released Undertale instead. Soon after Undertale's release, Toby went to work on the Deltarune we have today. Odds are, he had that sprite made for Undertale, didn't end up using it, and later reworked it for Deltarune's human, Kris.
