Yenom Frog

Yenom Frog (ネカガエル, Nekagaeru) is an amphibian animal that was killed by Hero in Castle Town, whose body is located right outside the south exit.

Characteristics
The Yenom Frog is a rather large, frog-like creature with a green body, yellow underside, big yellow eyes, and a pink tongue that can stretch out. Unlike a frog, however, it has two ears that extend from it's head and only two limbs.

Hint
The Yenom Frog loves coins. Something nearby may allow the protagonist to offer a thing that the Yenom Frog may like.
