Here’s Bon Bon or her other identity known as Sweetie Drops. The Slice of Life episode was an interesting one to watch and see the lives of the background ponies that never get enough screentime to see how they live their lives. Seeing Bon as a secret spy was a cool concept as well.
 
She’s Lyra’s best friend and often needs to keep her in line during one of her shenanigans involving humans. Now that Bon is fully aware of tiny humans ending up in Equestria and also knowing that Lyra is the one responsible for all of it with the exception of Twilight only wanting to send one over only, she goes over to her friend’s house to look everywhere inside to check if she’s captured any, always starting with her bedroom, bathtub and music room first. Lyra always makes embarrassing and goofy smirks whenever her friend searches her house since Bon already knows what Lyra will do to any she catches, even if they showed up normal size since they’ll still be at a big disadvantage on anthro Equestrian turf. There are a few humans hiding inside Lyra’s house and Lyra knows it, but can never find them since they can hide well from her. She placed a magical barrier in her house to trap only them in till she catches them, but Bon Bon arrives mysteriously to search her house as Lyra always gets close to finding them. A friend like her is needed to keep Lyra in line.
