Splendora Agatha Cromwell (Halloweentown)
Aggie is a fabulous grandmother (perfectly portrayed by the late, great Debbie Reynolds) who floats around in glittery cloaks teaching her grandkids all about her favorite holiday while trying not to fully reveal the family secret. The best part? She’s a powerful good witch from a magical town and wants to train Marnie to be a powerful witch, too.
