When I die in DeepNether , That blur appears over my NameLess crow 
Skill issue smth… 
yeah, it happens to me few months ago, idk what cause that
Is that part of the crows death animation? Try respawning with your crow and seeing if those pixels still are shown
Familiars don’t have a death animation , they just get sad that you died 
I think every pet has the blurred pixels, tried it with an unnamed gemmy and it still appeared
They do, it’s pretty obvious with some of them as well

damn that’s an illegal name for your pet
