Do the Pyre wood village quests only if you have a group. These should be done around level 16, but the rewards habbo credits are pretty good. There is also a quest which will take you to Ferris Isle to kill an elite named, bring some friends.
Head back to the Barrens when all you have is orange and red missions. You’ll either want to grind harpies or do more quests. The oasis line of quests is fairly easy and the XP rewards are not bad at all. Mushrooms grow by the oasis lakes and you put the seed in the bubbled-crack in the southern oasis.
If you have a group, now is the time to do Wailing Cavern. This isn’t an easy instance for new players; the end involves a giant murloc. No one ever finishes all the quests on one run to the cavern, so don’t expect to.
There is a quest to kill a goblin within the no instanced part of the cavern and habbohotel coins there is also a mission inside the eye of the scull shaped rock that is the caverns that you’ll need to drop down from the top to get to.
There are also Ogres in Alterac Mountains (just north of Hills brad Foothills) that have very few hit points and can be killed in quick succession. This can make for some quick experience gain and habbohotel coins decent humanoid loot.
