Uh, Baron's more of a worm than a dragon. There's also the dragon that gives 190g to all members of your team when slain, as well as Baron who gives 300g to each and an awesome buff to your whole team. Other mobs in the normal jungle depend; sometimes they're just safe, easy gold while you're in the area or something. There are also 2 groups of jungle mobs that are in each team's jungle that have a long respawn timer, but give special buffs for being killed. You can identify them by the fact that they have a pair of small lizards with them, and the fact that they have either a red or blue animation spinning around them. Getting the killing blow on either of those gives you that buff. Those buffs/the jungle monsters that give them to you are what people are talking about if you see someone talk about "red" or "blue."
