✦ Geese like creatures who care for Cosmos' Library.
✦ All seem to like to wear vests made of various patchwork cloth.
✦ No talk. Just H O N K.
✦ The tallest to smallest. Teacup, Oolong, Rooibos, and twins, Jasmine & Mate.
✦ Teacup, being the oldest and biggest, is also the loudest, angriest, and wears corderoy and plaid vests.
✦ Oolong is very quiet, somewhat mild tempered (for a goose). He wears pastels and polka dot vests.
✦ Rooibos likes to sneak up on people; does a terrible job at it, 100% will see him. He wears bright orange and camo vests. Also the chonkiest of them all, Celyn brings him snacks. Or he seeks out Celyn for snacks. Who knows anymore.
✦ Jasmine likes to hide eggs in people's shoes. She wears a mix of chevron and floral print vests.
✦ Mate, like Jasmine, likes to hide things in shoes. His vice; thumbtacks. He wears horizontal and vertical stripe vests.

It would depend on who is around, what time of day it is, what their moods are, the weather, the alignment of the stars, if you brushed your teeth or when your birthday is.
Unpredictable but somewhat mannered, The Gentlemen are what Cosmos would consider doughnut holes. AKA in normal people term, assholes.
They won't hurt you, but dear god, they'll terrorize you if you dare show even 1 ounce of weakness.
