The older sibling, Trish Genetica is 13 years old and aspires to be a detective similar to her father. She'll often drag her little sister along to solve mysteries with her, like trying to find the gnomes that stole her socks or whether or not rat people are running a secret crime organization in the sewers.
She's also trying to master her magic powers, though she isn't as gifted as her mom and Tilly and can only do minor spells like dye her hair.
The younger sibling, Tilly Genetica is 9 years old. She has her mom's love of pranks and likes to mess with "Auntie" Shannon, often turning her back into a kid and treating her like the older sister she wished Trish was. Shannon is also occasionally dragged along to join Trish's mysteries.
Tilly is also a lot more gifted when it comes to magic, being about as strong as her mom when she was that age and aspires to either be a great witch or queen of the fairies.
