Mobs and inventory are... pink?

Hi! This is my first time writing about an issue, so I'm not too sure what I'm doing. Please bear with me!

So, pretty much what's happening is, when I load the game, random animals, villagers, hostile mobs, chests, and my inventory are bright pink. I'm not too sure how to fix this, even though I've restarted the game and turned off the PS4. I don't have an image, and when I take a picture of my screen it's super fuzzy looking. Sorry for that.

I have no idea how to fix this D:
