Sweetie Drops, or Bon Bon, is a female Earth pony with a beige coat, pigment blue mane with a rose pink streak, cerulean eyes, and a cutie mark of three objects which are identified by Little, Brown's Mini Pony Collector's Guide and Gameloft's mobile game respectively as three candies and as three bows. She has speaking roles in Call of the Cutie, Green Isn't Your Color, Lesson Zero, The Super Speedy Cider Squeezy 6000, Putting Your Hoof Down, and Slice of Life. The name Bon Bon comes from "bonbon", which is French for "candy", and originates from Sweetie Drops' cutie mark's resemblance to wrapped sweets.
Design, development, and production
Sweetie Drops shares her design and coat and eye colors with S05E21 Unnamed Earth Mare #1, her design with Shoeshine, Luckette, Lilac Links, Grape Delight, and Sunny Smiles, and her coat and eye colors with Fine Line, Press Pass, "Roma", "Paisley Pastel", S04E20 Unnamed Earth Mare #1, and "Hazel Harvest". Her cutie mark resembles that of a G1 pony named Bon Bon while her color scheme is similar to that of the G1 pony Gingerbread.
Different merchandise name her Sweetie Drops and Bon Bon. Additionally, she is referred to as Bon Bon in the Japanese television broadcasts of Swarm of the Century and Green Isn't Your Color, she is named Bon Bon (ボンボン, Bon Bon) in the closing credits. In Slice of Life, she is referred to on-screen as both Bon Bon and Sweetie Drops.
Sweetie Drops frequently appears with Lyra Heartstrings, which has been explained by a layout artist to be mostly coincidental and based on aesthetic considerations, as far as season one is concerned. Being a background pony, she has a different tone in her voice in each of her speaking roles.
As with most background ponies, Sweetie Drops's design and color scheme are frequently used for filler ponies in crowd scenes. For example, in Fall Weather Friends, four or five Sweetie Drops can be seen as the angle pans past right before the race. Another four or so can be seen in the race stampede afterward; however only one is in the actual race. In a scene from Owl's Well That Ends Well, there are clearly two Sweetie Drops visible. She is also "doubled" near the end of the Winter Wrap Up song, right before Twilight Sparkle's finishing part, as well as many other times and places.

In Applebuck Season, she is one of the characters lining up for free muffins, and is one of the ponies who fell ill after consuming them. In Swarm of the Century, she is praised by Twilight for her good work on tending to the flowers.
