Make a tiny fictional moon landing on a cushion

My safe surface is [SURFACE] and my available harmless objects are [OBJECTS]. Design a five-minute fictional landing mission with a mission brief, three discoveries tied to actual textures or shapes, a nonverbal success signal, and a return-to-base ending. Supply a fully imagined version for someone who cannot or does not want to handle objects. Do not require throwing, balancing, cutting, or leaving a mess. Check that each discovery can be made with the supplied items and that the mission clearly remains make-believe.
