Each docodori is filled with a combination of the following substances:
black-nbluto (melancholic): a thick, dark, opaque paste that freezes and melts easily, but at varying, inconsistent temperatures. More study is needed.
enziomatic mustradictone (choleric): a brown fluid that breaks down human skin, flesh, and bone, but does not effect any other animal in a similar way.
yelourichrom (phlegmatic): a grey gel that remains at a constant 66°F regardless of external temperatures.
bloodwater (sanguine): a thin, translucent-red liquid that acts as an attractant to animals (including humans).
