God's Thumb is a fictional rock formation on top of a mountain that is part of the plot of the 2003 live-action film, Holes. God's Thumb is close to Camp Green Lake in Texas. When there was a lake, God's Thumb was on the other side of the lake. At the top of gods thumb there is a natural spring. Sam had his onion fields on top of God's thumb. After Stanley Yelnats I was left stranded in the desert, he found his way to God's Thumb and the spring. When Stanley Yelnats IV escaped Camp Green Lake to find Zero, they made their way to God's thumb also. Stanley and Zero ate sweet onions that were still growing by the spring, and drank the water from the spring, as Stanley sang the pig lullaby to Zero. Stanley and Zero broke the curse, which caused Madame Zeroni's powers to make everything back to normal.
