Yoda is a product of the 80’s so it only makes logical sense that when he wasn’t busy filming Empire Strikes Back and Return of the Jedi and doing his various Jedi duties along with his normal household chores like dishes and taking out the Jedi trash, that Yoda would go out and do regular stuff that people in the 80’s did- like tagging graffiti walls with your own name written below giant boomboxes while wearing a sideways baseball hat. Cause that’s pretty much what most of the 80’s was like. Graffiti and Yoda. Oh and LEGO. Can’t forget LEGO.
