Brown Wool, is often used in their Minecraft "Topia" series. This term originated during TreeTopia, when, after deleting their previous world, Jordan was tasked with building a Carl out of brown wool, to right his wrong, and was not allowed to mine, or do anything else unless it related to building Carl. Little did they know, their world had almost no brown sheep, and no Coco beans. Jordan searched for multiple sessions to find the items he needed to free himself. After finding his items, he built the ugliest Carl in the history of the Creature Hub.
Nowadays, in the CreatureTopia Series, their world is littered with brown sheep, which is a constant reminder to Jordan of his struggles. Often James, Aleks, or Kevin slaughter those sheep to further enrage him.
