At the end of the episode, the job center sends Shelby to a new job and it's at a crematorium for companion animals and we see her use a giant flat shovel thing to lift a dead white fluffy dog into an incinerator. it's played for laughs
when matty goes to push the manatee back out to sea, the manatee is dead and he graphically (accidentally) pushes his face and hands into bloody flesh. it's clearly fake but still extremely disturbing and goes on for a long time
