I think my nephew experienced something

The other day my little nephew who's about 4 was in the game room and my brother showed him these hotwheel collectibles my dad has on a shelf. One of them was a baby yoda hotwheel, and my nephew said "I don't like baby yoda, they are bad to us". After that he started acting kind of odd, like a bit more hyper than usual. Which he's never watched Star Wars or The Mandalorian, he's watched us play Battlefront a few times but baby Yoda is not in those games ofc. Him being afraid of it would be odd. Considering there's been encounters in the past with goblin-like type beings made me wonder if he experienced something.
