I'm sure we all know the pain of the gorilla asking for an impossible marking no one uses. A long time ago, this probably helped the lion population. But now that no one uses these marks anymore, these requests have just become plain annoying. I suggest the gorilla's marking requests be revamped.

For mane colors, the Gorilla should be able to request any mane color, as most lions have a non NCL/custom mane color.

Instead of being obscure markings, they could be marking colors or marking shapes instead. For example:
Bring us a cub with the following requirement:
1. Briar colored marking
or:
Bring us a cub with the following requirement:
1. Marbled Unders shaped marking

and for difficult quests, they could also ask for a rosette mark, like the following:
Bring us a cub with the following requirements:
1. Rosette marking
2. Female cub
3. Normal mane
