Let's go over the species!

Dicers

The die acts as their core and the spirit is able to change form into the dicers we know! Dicers can have any animal like snout/face. mammal or reptilian. If the Dicer is harmed or is low on energy it might decide to "recharge" and go back into dice core. It can reform when it feels it's ready

 The die can be anywhere on the body. It can be the nose or even get creative and have a horn to act as a cool shaped die

Masklets 

Masklets have a see-through membrane on their paw pads, stomachs, around their eyes, nose, and in their ears revealing a slime, magic, or space like substance. This substance can be opaque where you don't see bones or translucent where you can see the bones within. Masklets celebrate individuality by creating masks or having masks be made to represent themselves. Think of it like wearing a graphic tee shirt of your favorite band or show. Masks can be adorned with almost anything.

Masklets come from the isle of Moondrop off the cost of the mainland. If a Masklet is seeking adventure they will travel to the mainland to the Kingdom of Keydice.  

Over all Masklets are positive balls of fluff and are social butterfly's. The introverted ones are still social but it is widely Accsepted that if an introvert needed to leave a party or hang out early then they can with no judgement.
