Dust constantly takes care of injured animals, especially endangered or nearly extinct animals, before he lets them back out to wild.
He may or may not have also adopted a pet snake, who he named Slithers.
The only people who know about Slithers are Horror and Killer because once Slithers snuck into Dust's coat before a mission, and he ended up protecting Slithers from harm.Dust may or may not have also cried afterwards and Horror may or may not have had to cuddle him with Killer for a few hours to help calm him down.
