Thank you for your replies!
A lion's eye teeth are actually even larger than 15 times the size of other teeth in real life, and there really is no point making body tokens for every single animal.
Huh, yes, never thought about that. I thought that there maybe was a missing dot between 1 and 5.
As for the fingers, maybe the problem comes from this part from c_variation_default:
[CV_CONVERT_TAG]
[CVCT_MASTER:BODY]
[CVCT_TARGET:QUADRUPED_NECK]
[CVCT_REPLACEMENT:HUMANOID_NECK:3FINGERS]
I'm not sure, but I think this tag puts three fingers simply because the creature have the QUADRUPED_NECK tag, and then it puts more fingers because of
[CV_CONVERT_TAG]
[CVCT_MASTER:BODY]
[CVCT_TARGET:4TOES_FQ_FINGERS]
[CVCT_REPLACEMENT:4FINGERS]
