There are two stories explaining how Glub-glubs made their way into modern society.
The first one involves Mayans, spaceships, and secret agents and is about some Glub-glubs making their way to Earth before we realized that Glub-glubs were real. We'll keep the details of that story a secret in case we want to make a movie of it.
The other version is how it really happened: Jacob Rose was doodling in his planner one day, drawing creatures small and round enough to fit into the square divisions of his planner; squares that would later be labeled as containment cells. Before a conversation with his friend Anthony Fortner was over, these creatures had been named "Glub-glubs." They needed to explain the laser-field containment cells that had been drawn over the boxes printed in the planner, so they came up with the idea that there were some ambiguous bad guys called "Waka-wakas" that were keeping the Glub-glubs contained. Soon enough, Jacob and Anthony's mutual friend Alex Janzen heard about Glub-glubs, and in subsequent discussions the premise of Doodle-dood World was expanded into about what it is today. The name for Soh-Cah-Toans was suggested by Alex, who was taking geometry at the time. From there, Glub-glubs were created prodigiously. The first of Jacob's doodles was later named Dragon Glub-glub, and the original drawings also included Diamond Glub-glub, Fire Glub-glub, Super glub-glub, Evil Glub-glub, and Superintelligent Bubble Glub-glub. The list expanded to other planners, many pages of binder paper, and so on. By the end of the year Jacob's planner alone contained roughly 180 unique Glub-glubs. A little more than a year and a half later, Glub-glubs got an app. Alex's father, teaching software engineering at a local university, wrote the code for the first version of Daily Glub-glub, which was released onto the Android Market on September 1, 2011. Since then, Alex has drawn, written a description for, and published one Glub-glub for every day, and the list of all known Glub-glubs is upwards of 30 pages* and growing. Glub-glubs have also achieved their own website (which you probably already knew) as well as a Facebook page.
