Goblins. They’re truly the most treacherous of all the tiny hell beasts, often feigning loyalty only to stab their masters in the back.
Should goblins be sold as house pets? Sure they might wash your laundry but I’m pretty sure they’d kill you in your sleep. Better to get a dog that will just lick your toes.
Note that goblins will also lick your toes while you sleep but they will also masterbate and speak in tongues as they do so.
Nope I just cannot advise you to let a goblin into your house.
