Stone giants

Stone-giants first appeared in the Hobbit (Also called There And Back Again).It was their only known appearance.They first appeared in chapter 4 (Over Hill And Under Hill),where they are described as hurling rocks at one another for game as the rocks fell off the mountainside crashing atop the trees below.Bilbo,Gandalf,and the thirteen Dwarves were the only ones to have ever seen them.Their physical form was not explained,nor was much else about them.But from what is told we can only imagine they were probably not very clever folk,and most likely very reckless,since they were thoughtlessly tossing massive rocks for fun.the rocks were explained as smashing the trees they fell upon,therefore they must have been very large and very haevy, therefore the giants must have been very strong,without the obvious knowledge of being a giant.Also,the stone-giants were said to be able to reach heights as tall as forty feet high,as only told in the Red Book Of The Westmarch.Again, they must have been either very unintelligent or very fearless for dwelling in the Misty Mountains,where goblins abide.
