The monkey on the rock is known as Sun Wukong(son Goku in japanese) he is not a basis on Son goku from dragon ball (Z). In fact, it is the other way around.
Sun Wukong is from Journey to the west, a chinese story created 15 centuries ago wich is why not much people know about him.
The follow characters are Tintin, a boy reporter from the adventures of Tintin by Hergé, then there`s kid Goku and kid Vegeta!
sorry if it isn't very clear and has sccribles on it... i didn't do a good a good job on the editing. :P
