Fics like Lurking Variable

A child with a cowboy hat and delusions to becoming a sheriff decides to stay with an old goat rather than staking it out on their own. Big consequences follow. AU where the Sixth Human, the Yellow Soul, stays with Toriel instead of proceeding onwards into the rest of the Undertale. When Frisk arrives in the underground, they have some help, though considering its form they might not want it.
