a dead pegasus
Death does not always come in one form, it can take other shapes.
This mystical creature died a naturel death and was resurracted by wizards.
Only the skin, eyes, tongue and it´s skeleton is left.
It will live as long as the wizards want it to live and it will live as long as the wizard or even longer depending on how powerful the spell was to resurrect it.
Done with pencil work and a ink pen.
