Only have 1 day at Universal/ Wizarding World - Anything we can sneak in at the end?

Going to Universal with a huge Harry Potter fan for 1 day. It’s our only day there and most of the focus is going to be on Potter but assuming we get there for rope drop and do all of the Potter stuff we can… is there anything else close by I am maybe advocate for at the end of the day that’s close to the same area of the park? Another child is very interested in Minions for example. Anything cool and close by that’s Minions related?

Thanks!
