I was listening to Let Me Be Surprised
and I couldn't get this image out of my head, haha. Realistically Gaster would just shrug and be like guess I'm dead but whatevs. Also Healie doesn't really work for this but I just really felt like drawing Healie, don't judge me.
Healie (c) Dragon Warrior IV
Gaster (c) Undertale: dang that sans i'll kill him
