The real reason for Gaara loosen his mind.
The little tiny dancing monkeys in his head were angry they wanted revenge. They snuck out of his head in the middle of the night. Gaara chased them but was knocked unconscious by the biggest of the monkeys. They negotiated with Temari and she agreed.
The little monkeys danced back into his head and before Gaara knew it. IT WAS SHOW TIME!!
