Friendship is likely a theme, as it is in the main My Little Pony series. Maybe the pony puppy has to make friends with other ponies or creatures in the 'other stories'.
Adventure could be a theme too. The pony puppy might go on a journey through the My Little Pony world, facing challenges and learning about new places. It could also be about discovery, like the pony puppy finding out about its own special abilities or a hidden part of the world it lives in. Another possible theme is cooperation. The pony puppy might need to work with other characters to achieve a goal, whether it's saving their home or helping a friend in trouble.
One theme could be acceptance. The pony puppy, being a bit different from the regular ponies, might have to be accepted by the pony community. This could lead to stories about how differences should be embraced rather than shunned. Also, the theme of growth could be present. The pony puppy could start as a naive or inexperienced character and through the events in the 'other stories' grow into a more confident and capable being, learning important life lessons along the way.
