Of course, but I didn’t mean “once” once. They shoe-horned it in there to please Hasbro, and it was never an integral part of the character like the library was (or Applejack’s jalopy).

@Mildgyth  
But the balloon is apparently owned by Cherry Berry in the series. They should resell the balloon with both Cherry and Twilight, but because of Twi’s royal title right now, I don’t think that’s nessecary. I mean they COULD sell it with just Cherry, but Hasbro has been advertising the Twinkling Balloon with Twilight since the show began, and they think that only selling playsets with the Mane 6 would get them more money because children know who they are. I’d doubt they’d know Cherry, except for the people who have watched the show, which no offense, has only really been watched enough by us bronies.

But the balloon has appeared more than once.

It’s just going to be Twilight’s balloon again. We see it in one scene of one episode, and then it never shows up again.

I swear to Celestia we need to know how and WHY Pinkie can drive a swan boat in Season 6.

@TheOtherPinkiePie  
the mad trolls of Hasbro strike again.

@Joshua  
Well, I know. But I thought the swan thing was just toy-only.

Shouldnt this be marked as spoiler?

@TheOtherPinkiePie  
To be fair, the show was originally intended to sell the toys. That’s what hasbro’s shows tend to do.

So yeah, the swan boat thing is apparently part of Season 6.
