Neglected Yorick

you recently gave me pentakill yorick (which is awesome thanks a lot, i can't wait tor use him often), but i looked some stuff up and nothing really changes about him. The only thing i could think of was maybe for his laugh, he could play a guitar riff? OR epiphany just now, he could play a different riff , every time he activates an ability, so each ghoul would have his own theme song type thing. please and thank you
