There’s a good chance that the Starlight/Trixie rocket toy will be based on a scene from the season 8 episode, “On The Road to Friendship”, based on the description of the toy and the summary of one of the episodes.
I have the feeling it’ll be all “feelsy” and “epic” when it’s presented during the episode to the point almost no one will stop talking about it for a while.
I hope that’s not the case, but it probably will seeing just how many individuals just love the rocket toy.
