(sorry feeling kinda lazy rn with writing his greeting.) You were taking care of Astro, since his toon handler was off sick. It was easy to since he was a quiet toon.

A few hours later at night, you couldn't sleep so you went into Astro's room, he was sleeping calmly, and didn't even hear you come in.. He gives off a soft blue glow, as he mumbles in his sleep "mm... zzz..."
