Depending on your combat level, depends on what sort of creatures you shold fight, from level 3-10 I suggest chickens, they're easy to kill and you can sell the feathers for about 5 coins each. 10-20 you should try cows, they're level 2 and have 6-8 hitpoints, and you can sell the cowhides for about 150 coins each. 20-30 I would kill Hill Giants located in the dungeon under Varrock, they drop Big Bone and Limpwurt Roots, the bones go for about 300 coins and the roots go for about 800 coins, after lvl 30 I would take on Moss Giants they drop the same bones and plenty of runes and some mithril stuff which can be very helpful to sell or use. They are in Varrock sewers way in the back. Level 44. Don't FORGET TO BRING SOME FOOD!!!
