[2019] Pet clipped through my wall and vanished

Hey @Darkzombie

Did this happen in an online server, coop or single player?
If online, your rhino will come back to its last designated guarding spot after a designated amount of time, or on server restart (whatever comes first).

Glad to hear you found your rhino. He might’ve had a wild night.
What happens in the black galleon stays in the black galleon.
