Sharp

The Sharp is a subspecies of Gloople. When it senses danger, it will generate sharp nails on its skin, which will harden. In this state, a Sharp can easily impale humans, and its hardened skin provide it some protection, to a bullet-proof level. However, this has its disadvantages: an hardened Sharp can be knocked against other Glooples, effectively killing them.

Harden skin
A Sharp has this abillity as a mecanism of hunting and defensive uses, but how a Sharp is able to do it? Normaly gooples are alchool based Sharps are too but they theoricaly they could has a body based in carbon and silicon this hypostsis was created by observations in Sharp's structure, when hardened a Sharp has a bright look that sugeres a silicon presence in form of quartz cristals that are hard than steel, but sharp has la very good complexity that is created by carbon based organs.
