On this week's Disney Dish, Jim has some new details on The Magic of Disney Animation 2 - Electric Boogaloo.
Jim says this, the new show for Disney Junior, and the current Mermaid show is the 10-year plan for Animation Courtyard.
The most likely candidate for the new show in the Disney Junior space is Bluey, especially with Disney releasing the upcoming Bluey movie in 2027.
I thought these were more like 5-year placeholders. 10 years is a long time.
The new Mermaid and Villains shows are rated very highly (4.5 stars, much higher than the things they replaced). So the thinking might be that this is good enough.
