Humbah is the unofficial leader of the Boohbah. She wouldn't have been leader, but she pulled a Magnum. Humbah was created by the Teletubbies when they needed help. She actually wasn't the first one made, and Dipsy wanted her to be green, as he created them and wanted the first to be his. But She came out yellow, so She became Laa-Laa's instead, and Dipsy got stuck with Jumbah. She is very evil due to the evilness that was added when she was created.
