Grintongue Rattel

Grintongue Rattels are little farmers, bringing seeds from the Deadtongue Pepper near their lairs, burying them near the entrance. When near a grintongue's little lair, a body of water is often found, containing a Irithscale Lizard or two.
The pair of monsters have a symbiotic relationship, the leaves from the peppers are a favorite snack of the lizard, and the lizards themselves will chase off the predators of the rattels that make it past the peppers. They start to covering their nests mainly with fur from their own bodies and feathers from the Jadiwl Wing, and even sometimes a loose scale of the lizards as well. While not exactly comfortable, there is no reason other than the symbiotic relationship for the scales to be present near their nests.
Eating the Deadtongue Pepper makes their breath stinks, but also ferments in their tiny bodies. Upon eating the peppers, the rattles bodies form a toxin, which lasts for up to two hours. Their breath is also an irritant to themselves, turning them blue, and they will walk around with their tongue out too cool off.
They large eyes are considered milky when they have reached a high amount of deadpepper toxins.

Children are always warned not to touch the peppers, or a irithscale will snap you or blue tongued rattel will bite.
In villages that are thoroughly plagued with rattels, its considered bad luck if the rattels avoid a poor house, signifying that even the rattels find you too poisonous to be around.

Grintongue Rattels have recently been hunted and captured for a different reason; they are being used to make a new type of fast acting poison. Deadtongue Pepper themselves have been experimented on, however the effect of poison is not strong in the least, and is gingerly added to cuisine instead. But forming in the rattel's stomach, the toxin changes.
The rattels are made to regurgitate after five minutes of eating the peppers, before their eyes turn that milky glaze, and its kept in a vial underground. Some say its to ferment to be stronger, but it has been proven to lose potency in most lighting.
