+## Illustration guide
+
+Our hedgehog mascot is called Max and we're quite particular about how he (or any of his hoggy pals) are illustrated. We're exploring AI tools for internal use, but currently ask that you don't use AI tools to create your own hedgehog art. Instead, you can follow the guidelines below, or [create a new art request](/handbook/brand/art-requests).

+
+If Max is drawn in color he should always have a beige body with brown spines, arms, and legs. His arms should only bend once in the middle and he doesn't have fingers unless swearing or pointing. His feet are stubby by design and his snout lines should be visible unless obscured by a mask or beard. His expression comes mainly from his eyebrows.

+
+He should be outlined with a strong, black monoline with consistent thickness. He should always face left, right, or straight-on but shouldn't be drawn with a side profile or from behind as he's self-conscious.

 ## Hedgehog library
 
-For team members we keep all our currently approved hedgehogs [in this Figma file](https://www.figma.com/file/I0VKEEjbkKUDSVzFus2Lpu/Hoggies?type=design&node-id=0-1&mode=design&t=H3ElmuzbLMFp4qP7-0). This enables us to look through the library of approved hogs, and to export them at required sizes without relying on the design team.
