"One of Trevor's four children, and the only one that stayed with her father and Vajra. Her fur softly glows occasionally, like lightning is booming under it. Trevor had a clutch of Eggs with a female Poison Blend Rotom, and Tart was the second to hatch, as well as the only girl. The other three babies were given to other residents of the Cavern who wanted them, but Tart didn't mind - her clutch siblings, consisting of two Rotom and one Ghost blend Swirlix were fond of playing constant pranks on her (but only because they wanted to make her laugh!)."

Tart is named after the candy brand "Shock Tarts".
