Sophie Piper

Sophie Piper is the youngest daughter of Gwen and William Piper, granddaughter of Aggie, and younger sister of Marnie and Dylan. Like Marnie, she is also a witch. She can cast simple spells that she learns from her sister and grandmother.

Story

In Halloweentown, she is about 7 years old and can control her powers better than her sister can, as her grandma states it only takes the will and imagination to make magic work. She memorized the spell that Aggie used and Marnie figured out how to power the talisman.

In Halloweentown II: Kalabar's Revenge, at age 9, she can sense Kal's presence, which her grandmother, mother, sister and brother can't, but has a hard time controlling her flying abilities because Aggie hadn't taught her how to fly yet.

In Halloweentown High, she appears briefly not using any magic. She's about 12-13.

In Return to Halloweentown, she does not appear, but it is revealed that she has started her witches training under her grandmother. She has problems with her inner dimensional time travel. She's about 14.
