While fleeing from the Chessmen the Mock Turtle mentioned an encounter or encounters with the British heroes, Popstar and Larkspur, that occurred circa 1996.
- Possibly named after the flower popstar, also known as Chinese Foxglove. Used in Eastern medicine for its healing, longevity, and protection properties. This suggests that Popstar might hail from some oriental Country and possess healing and/or protection powers.
- Popstar might be part of a duo team, working with Larkspur.
