She was originally named "Bluebell the Wearable Items Mare" in the earlier Open Server Events.
Bluebell used to sell equipment that could be worn by the player. However, as of the 4/11 open server weekend, she now only sells food (and a saxophone, for some reason). Despite this, a few lines of her dialogue still imply that she sells clothing. She sells clothes again as of 8/15.
Bluebell has no talent mark. There is no explained reason for this.
In the ninth Open Server Event, her eye design was changed and a secondary color was added to her mane.
