Within the Epicness Universe
Yeast initially survived the breach into the Epicness Universe by entering the basement of the Mysterious House, where it grew large and fat, and developed a penchant for reading. When discovered by Pasquel FeelinSour and his two children, the resulting Yeast organism that had taken residence in the basement had began to refer to himself as the Globglogabgalab (the yeast of thoughts and mind), a being of immense power that was immediately compared to Pasquel by his children due to his weight and facial shape. Detaching some spores from his flabby body, the Globglogabgalab infected Pasquel and his two children with the Epicness Universe's first case of yeast infections. After they were all healed, the remaining yeast condensed itself into the Yeast Kidney Stone, one of the stones on the Infinity Jauntlet. This stone has the power to inflict yeast infections upon anybody it is used on, but it is currently lost to the world. It is brown, fairly small, and smells strongly of yeast. It also has the ability to make the holder twice as intelligent, as the Globglogabgalab's knowledge of books is locked within the yeast.
