In the Final Installment of Holiday Specials, Marty treats us to 3 more Holiday songs. From 'Spiderman, Into the Spiderverse' we hear 'SpideyBells' by Chris Pine, from 'Jingle Jangle Christmas' we hear Keegan Michael Key perform 'Magic Man G', and from 'The Nutcracker and the Four Realms' we enjoy 'Clara's New World'.
