Onrosuses eat all manners of vegetation, but their favorite food by far is watermelon. At dusk they emerge from the water to graze on grasses, and look for more tasty snacks. Young onrosuses who are more adventurous will sometimes try to steal food from the castle's gardens. They seldom succeed, because onrosuses can neither move quietly nor hide behind anything. Despite being less than talented at stealth, onrosuses do hide their eggs extremely well. Their eggs are actually buried in mud, so they're practically impossible to find. Several adult onrosuses remain near these eggs at all times, ready to chase off intruders. Another aggressive act takes place whenever two males are in the water at the same time. They become very territorial, and snort angrily at one another. Sometimes a chase begins. Despite being incredibly large and heavy, onrosuses can run for short distances very quickly. Otherwise, males are friendly towards other males. As far as anyone can tell, onrosuses have no particular social order. Their groups can be anywhere from a few to one hundred. Interaction is no different between males and females. As for telling the two genders apart, they are similar in size, but only males bear sharp tusks.
Now i just need my male to grow up so we can see if there any differences in the adults(I think there will be since the description mentions the males alone having large tusks)
