I found something interesting about this short

Apparently this short was actually supposed to be a segment of a third Fantasia film. Many sources confirm this. The other shorts that were originally segments besides this one were Destino, One by One and Lorenzo. The original trailer for the Blu-Ray release of both Fantasia and Fantasia 2000 mentioned a disk called Fantasia World and said that it would include never before seen shorts which probably implied this short and the other three. However when the Blu-ray was released, only Destino made it to the bonus features while the other three did not. That really ticked me off because if it had happened then it would have been the only way that fans would have a glimpse of the complete third Fantasia film and they would have included a "making of" documentary of these shorts. I don't why this short was found on The Little Mermaid DVD when it should have been the disk included with the DVD and Blu-Ray of Fantasia and Fantasia 2000 that should have had it.

Anyone else knew about this? I found that out on several websites. Roy Disney screened this short with the other three at a film festival in California which was one of the very few instances where this short was seen by fans.
