Mangarooka was the skinny and giggly, but devious leader of the Flitchaye. He gassed out and caught Alderjack, Treescamp, and Horlington Bradshaw Vittlescoff III to feed to Aszurass as a sacrifice, or as he called it a "Saggerfish". He spoke with the same primitive chatter as the rest of his band, and was even evil enough to watch travelers' fates while eating nuts, like popcorn at a movie theatre! He was caught by his former victims and the whole tribe was gassed out by their own fumes. He was terrified and uncertain of fire.
