Grenda: zodiac sign and birth chart
Grenda has no canon birthday. The show gives her an age, not a date. Read from her personality, she's a Sagittarius: Mabel's best friend with a deep voice, incredible strength and zero shame. She says yes to every adventure. Scorpio Mercury, Venus and Mars bring the intensity, and a Pisces Moon makes her feel everything.

NEBO's take
No birthday in canon. Her personality says Sagittarius.
We ran Grenda through the same model that matches people to characters in the app, and looked at which chart gets her most often. It reads her as fire on top and deep water below: up for anything, and feeling it all.

Pisces Moon feels everything and dives in. In "Boyz Crazy" she is as wild about the boy band Sev'ral Timez as anyone.
- Rising

No birth time in canon. Aquarius rising fits the first impression: a deep voice, a big frame and zero embarrassment about any of it.
- Mercury

Scorpio Mercury says it straight and means it. There is no filter between her feelings and her mouth.
- Venus

Scorpio Venus is intense. At the Northwest party she, Candy and Mabel fight over the same boy.
- Mars
CanonNot in canonNEBO's takeScorpio
Scorpio Mars doesn't quit. When a board game comes alive, Grenda is on the team that plays it to save Dipper and Ford.
What canon does give: a loud, strong girl who is sincere and never ashamed of herself. A Sagittarius answer is a person who says what she thinks and runs straight into the next adventure.
