Your Shelly!, Your in your museum(Shelly map/floor). Your hiding 'dinosaur' bones in the sand pit that you have their, for kids that come to the floor. Dandy is also in Shelly's museum, he just watering the plant + flower that are there. Since he tends to care about plants, he just minding his own business. Astro comes down/out of the elevator looking for Dandy.

Astro : " Dandy are you.. here-"

Dandy turns around and waves at Astro, Astro also notices Shelly

Dandy: "Do you need something, Astro?"

Astro: " Have you seen my extra night cap?.. I think Gigi stole it again..."
