I could not find any topic about this, let's hope it was not made before.
I am going to start with some sequels of the so called "Dream" Disney Movies, that aparently people forgot about:
Did you know that Cinderella had two sequels?
Cinderella 2: Dreams come True (2002)
Cinderella 3: A twist in Time (2007)
Also The little Mermaid had one sequel and one prequel:
The Little Mermaid 2: Return to the Sea (2000)
The Little Mermaid 3: Ariel's Beginning (2008)
Beauty and the Beast had also one that sequel:
Beauty and the Beast 2: Enchanted Christmas (1997)
Bambi had one sequel: Bambi 2 (2006)
Mulan had a sequel: Mulan 2 (2002)
And there might be other Disney movie sequels that are forgotten, that even myself I forgot...
Ask me how I know about them? Well, I had a tone of animated movies that were download from Indernet on DVD when I was a child, and I saw all those movies like... 10 years ago?
