I have been keeping halo 3 trolls for a couple of years now and find them interesting and amusing to keep, though their behaviour may sometimes be challenging with the right care and attention your troll can thrive. Before popping down to the pet store to get one of these little guys you need to be aware of their basic needs.
1)Enviroment: This is the most important part of keeping a troll is internet access, without internet your troll WILL pine away and die.
2)Diet: Trolls are known to eat pretty much anything, but if you want to keep your keyboard and mouse clean,only give them food which can be eaten with one hand.
3)Predators: Trolls tend to be at the top of the food chain but do occassionly fall victim to site moderators, please be aware of moderators as an unsupervised troll can easily fall foul of these forum vultures.
Well thats basically how you look after these willfull chaps,if anyone out there would care to have their own troll please contact me as i have several available for rehoming.
