Tootsie Flute

Tootsie Flute is the fan name for a filly used as a background pony in. Within the fandom, she is primarily known as the daughter of Bon Bon and Lyra, either adopted outright or brought into the family via magical means (as in the story And Tootsie Flute Makes Three by Dlazerous). She first appeared in the episode Call of the Cutie, and her relationship with Lyra and Bon Bon became the subject of fan art within days (e.g. this image from January 10, three days after the episode aired). However, since the episode The Mysterious Mare Do Well, which showed her at a picnic with Sparkler, some fans consider her Sparkler's daughter instead of Lyra's.
