Bokudile
Description:
A bokudile is a large, amphibious creature inhabiting tropical rainforests, swamps and wetlands. They have rubbery skin, like, that of a frog, but run on the their powerful hind legs. Bokudile mostly feed on river fish and crustaceans which they catch by diving into the water with their wide mouths agape and then filtering them out using baleen-like filters.
Bokudile are not aggressive, and not particularly dangerous, and they seem to pay no mind to most humanoids. They will almost never attack and will almost always flee when threatened. In many cultures where people live in small riverside villages, having bokudiles around is considered good luck, and the skill of spotting and tracking the movements of bokudiles is helpful for fishermen, who can predict where fish will congregate based on where bokudiles are known to be feeding at any given time.
Because of their size, speed and realtive passivity, bokudiles have been trained to work as mounts in some tropical wetlands. They can be easily saddled and controlled if raised to it from a young age, but they won't breed in captivity, so their eggs needs to be gathered from the wild in order to raise new mounts. They are not very intelligent, however, and are prone to suddenly and uncontrollably diving into the water for food. They cannot be ridden or controlled while swimming, so when this happens, the rider will normally be forced off, injured, or even drowned if they fail to free themselves from the riding tackle.
Bokudiles are too timid and skittish to be trained for mounted combat. A bokudile can be trained to carry a rider, but will not carry a load on its back.
