Patsy is a cute peppy mongoose from Acorn Flats. She is voiced by Jodi Benson, who is well known for voicing Princess Ariel from The Little Mermaid series and Kingdom Hearts series, and Helen of Troy from Disney's Hercules.

Patsy is a perky, adventurous Squirrel Scout whose friends are Nina, Gretchen, Almondine and Amber. She occasionally gets along with the bean scouts, such as helping them hunt a snake, but can also find them annoying. Her love for Lazlo is a running gag throughout the series. Patsy also enjoys reading scary stories to her friends. Patsy can be considered the ringleader of the Squirrel Scouts. Most of the time, Patsy is the instigator of the girls antics, and the other girls willingly follow her lead. In It's No Picnic, she argues with Bean Scouts about muddle. In Marshmallow Jones, she roasts marshmallows with her friends. She observes Bean Scouts in Beans Are From Mars. In Dosey Doe, she meets Lazlo in Camp Kidney's Mess Hall. In Snake Eyes, Patsy is a snake hunter. In Miss Fru Fru she searches on encyclopedia what is "fru fru". In Love Sick, she helps Nina, Gretchen, Almondine and Honey win a tug of war against the Bean Scouts. In I've Never Bean In a Sub, she eats a grilled cheese sandwich and works as a cashier for the Squirrel Scouts' cookie business. In Snow Beans, Patsy joins in singing on the bus trip and she was afraid when Lazlo along with Lumpus was gone, for her fears are when Lazlo disappears.

However, Patsy will go to any lengths to protect Lazlo, such as beating up all the other campers (including Lazlo himself) to prevent her father from finding out her crush.

Patsy has bright pink hair. She wears a Acorn Flats' uniform with an scarlet vest, dark blue shirt and skirt, dark blue beret, and dark brown shoes.
