Here are the two animated shows I think would make great Broadway Musicals in the future:
The Loud House (en.wikipedia.org/wiki/The_Loud…)
To be honest, I think it will make a great musical. I was inspired by You're a Good Man, Charlie Brown (en.wikipedia.org/wiki/You%27re…) for this. I'm not sure if the musical based on The Loud House will be similar to You're a Good Man, Charlie Brown (just like the original The Loud House being similar to Peanuts), but I think it is a great idea. If it was real, I'd probably go and watch it.
The Mr. Men Show (en.wikipedia.org/wiki/The_Mr._…)
Don't get me wrong, I think it will make a really great and funny musical. I think it will still have funny skits just like the original show. But I also want it to be focused on either Mr. Bump or Little Miss Calamity, who will try to deal with their unlucky lives. If this musical will be real, I'm sure the kids will enjoy it.
Of course, I'll include those shows in the meme that I made: Top 10 Cartoons that should be Broadway Musicals m, once I get more shows for the list.
