This is old news but my wife and I watched all of the new (2013–2019) Mickey Mouse Shorts (usually 3.5 minutes) on YouTube over the years and unsurprisingly, now that our toddler is old enough, he loves them too. It is about five or six hours of material. He watches all of it in about a week!
I found out that I share a birthday with one of the main characters. I also found out the Disney is working on a theme park ride based on that Rainbow Caverns episode called Mickey and Minnie’s Runaway Railway. Surprisingly this is the first Mickey-themed ride-through attraction!
