I think the theme is friendship because because Stanley taught Zero how to read and zero helped Stanley dig his hole and after Zero ran after smacking Mr Pendanski in the face Stanley was determined to find Zero even though Zero ran and was nowhere to be found. after that they climbed gods thumb together. Even after getting out of Camp Green Lake Stanley split the money with Zero so Zero can find his mom and for Zero to live with Stanley.
zero look onions and the stream!
Stanley and Zero ran away from camp green because zero hit Mr Pendanski in the face then Zero ran. Then Stanley drove Mr Sir's truck into one of the holes and Stanley ran. Then Stanley found zero under a boat and then in the boat there was this drink called splosh. Then after they had splosh they went to climb gods thumb.
Zero passed out from lack of water and food and then Stanley had to carry zero up gods thumb.
Stanley poured water on Zero and then he woke up and they both ate onions and drank water. So Stanley's great great grandfather was supposed to carry to carry Madame Zeroni to drink water and if he didin't he and his family will be cursed for all eternity and since Stanley took Zero up the mountain and he is related to Madame Zeroni so it broke the curse that Stanley's grandpa had.
Stanley and Zero found a chest from Stanley's great great grandpa and the warden, Mr Pendanski and Mr Sir were going to leave them to die but since they ate onions the yellow spotted lizards didin't bite them. They climbed out and the warden tried to take it but zero learned how to read by Stanley so Zero said look it says" Stanley Yelnats" and they took the chest with them.
So Stanley and everybody i camp green lake came to Stanley's new house and Zero finally found his mom by his money from the chest. In the end Stanley and his parents and friends including Zero found a new house and are out of Camp Green Lake.
