These are really great MU crossovers. There’s some that I’ve seen on the internet that crack me up myself, usually parodying TV/movie promos, such as this one here.
Keep 'em coming!!! I’d like to see what others you come up with. 
Sorry to say but the final day of crossoverstravaganza is here. (Dramatic Music) I hope everyone had some fun with it and I hope to stick around for a while.
Day 7: Monsters In Black
Agent J is gonna make sure that no monster’s are coming into our world anymore.
I’d say you’ve done a spectacular job this year! They’re so much fun Applauds
Can we have more cross-overs, this time with Inside Out and The Good Dinosaur involved? Please?
