Cauldron Bubbles

Cauldron Bubbles was the shop keeper of Magic Shop, a shop that sold magical goods, items and animals for relatively minor prices. She was a theatrical, energetic and money-grubbing mare who knew how to manipulative ponies into buying her wares in mass. She also carried around a staff with a blue orb on top and seemed to enjoy teleporting around to make an appearance.

History
When Twilight Sparkle and Rarity visited Magic Shop, Cauldron appeared to greet her, but when Twilight tried to find out about Shadow Lock, she insisted Twilight buy her stuff before she told her anything, it was a store policy afterall. After Twilight bought over 42 bits worth of items, Cauldron "finally remembered" Shadow Lock and told her what she knew.

Personality
Cauldron Bubbles was an adult mare with a purple coat, blue mane and "spiritual" regalia depicting flowers. Her cutie mark was that of a large, Jupiter-like planet with a yellow ring and she wore a white apron.
