While giving more experience per catch than the draconic jadinkos they seem to give slower experience rates due to them having a seemingly low success rate for trapping; even at high levels. In addition to the "chunk" experience bonus given by Papa Mambo for catching all three in a given week, there is a thirty minute experience bonus given to all Herblore habitat related Hunting, Farming, and Herblore training. This time begins when you collect your chunk experience bonus and will end upon log out, so do not collect your reward unless you are ready to use the thirty minutes or do not care.
