One evening, the mane 6 and their allies came to the Night Market, everything was going well until there was the encounter with the enchanted glitter, causing them to become foals. Upon turning into foals, there's chaos at the market, alarming Alphabittle and Queen Haven immediately.

In the midst of the chaos, Misty notices her dad and she reaches for him, out of surprise, he says, "Misty". Misty's mannerisms reminding him of the old days. But that wouldn't last as the other loose foals were causing problems, shattering of pottery, getting into the food, and messing things up. Sparky tries to help, but the foals being close to his size, there wasn't much he could do but try to hold them back, but there were no guarantees that would last long since baby ponies are known to be very strong at a young age.

And yes, this is loosely based off of the events from a Tell Your Tale episode, but this is slightly different. One difference is, the foals are in this state for days so the adults had to deal with them until an antidote was found to turn them back. They're reminded of how hard the foal stage is in that time.
