Favorite stuffed animal?

My son loves his shark stuffed animal. He sleeps with it, goes everywhere with it, and ultimately it’s starting to get filthy. I have to prive it away dying bath, bc he wants it in the bath. I am ordering a new one cause washing it doesn’t do much for the yellowing. Anyone else’s toddler have their favorite stuffed animal? Also, the shark is his pretend baby. That shark has oranges, chocolate chip smears 😅
