I would have loved to have seen other pony kingdoms shown. A kingdom in the stars where the Sparkle Ponies as well as the Glow 'n Show Ponies live would have been really neat. An underwater kingdom where the Sea Ponies and even Fancy Mermaid Ponies lived. Some kind of tropical paradise where the Tropical Ponies and second set of Flutter Ponies lived.
YES!
I loved reading the story of the Sparkle Ponies in the leaflets who lived on Glitter Island. And I just love the way they illustrated them in the comics, they really looked sparkly! (Though that might have been too much detail for animation. But hey, it's a dream
)
And it would be cool to meet the Tropical ponies whizzing by on their surfboards!
And definitely more Mimic. I loved her in the cartoon. Did she even have any lines?? I don't remember ever hearing her voice.
Paradise telling stories. She was just amazing!
And more Megan. Maybe she meets a handsome... wizard/prince/elf/guy and it turns out he's not to be trusted, and she learns some lesson about friendship or honesty.
All of the episodes were so imaginative, I don't think they'd have too much trouble coming up with a whole bunch of great ideas
