Umakavi

A small tree frog from the rainforests of the Mûmakan in the south of Middle-earth, the umak is notable for the potent contact poison umakilis exuded by its colorful skin. Bright lime green and streaked with yellow and orange, the umak tree frog is noticeable, but it is so rare that it is still nearly impossible to spot.

The bright coloring warns away animal and bird predators who would be poisoned upon grabbing the frog in their beaks or mouths, but merely makes things easier for clever Men or Elf hunters who wish to extract the poison and who come armed with nets on long handles. The poison is tenth level in contact with skin; unlucky individuals are killed instantly (upon failing a RR), while the more fortunate are plunged into a coma until awakened by some form of anitdote.
