And up there is big skeleton and little skeleton
A Patreon reward! Another set in the Mercy scenario where Gaster took them out as babies and tried to raise them as normally as he could, meaning everyone is mostly trauma-free. In this case, they wanted Gaster showing them the stars on the surface! I wonder if the skeletons had their own constellations?
