During one of their visits to the great tree, Bubbles showed a piece of isinglass (mica) to Eglantine. Eglantine began shaking as she remembered something deep and broke out of her trance. Bubbles was panicked by the reaction.
While Trader Mags was out on a business trip, she left Bubbles in charge with a few rules. A rogue smith stopped by (who was actually Nyra in disguise). The rogue smith was interested in the green eyes and gave a piece of silver art and her tongs, describing the trade as "art for art." After Trader Mags returned, she was upset that Bubbles traded all her green eyes and was angry at her for not realizing something was wrong, as the rogue smith of Silverveil was the only one who worked with silver.
The band was trying to gain information from Trader Mags about the Book of Kreeth. When Twilight ripped off her bandanna in irritation, revealing her bald spot, Bubbles was quite shocked.
When Bubbles and Trader Mags arrived at the great tree, Octavia told them there wouldn't be really any calls for their wares today, due to the mysterious Striga. Octavia then told her that Trader Mags had someting interesting for Otulissa. Bubbles thought the snake was talking of their wares and was sure Otulissa didn't want any. Trader Mags scolded her for her misunderstanding.
Bubbles is a foolish magpie, who is very trusting and doesn't bother to think twice. However, she is kindhearted, and is very chatty. She is very loyal to her mistress, Mags.
