Yooka and his family lived in Maui, Hawaii. His mother raised him and his three siblings while his father worked at NSA. One day, Yooka's mother got a phone call saying that Yooka's father and his co-workers had died in a rocket explosion. Rather than grieving, Yooka bottled up his emotions, and sat in front of the TV.
Yooka's mother decided that it was time for a change, she told the whole family that they were moving to Mexico. Week after week of Yooka watching TV, his mother decided to take action, and sell the TV. This infuriated Yooka so much that he decided to leave his home, and never return. For the next few months Yooka slept in his friend's garage, and made money by doing odd jobs.
One day, Yooka's mother found him and had fantastic news. Yooka and his family had inherited over twenty-billion dollars from his late Uncle Banshee. With the money, Yooka bought a mansion back in Hawaii and the largest screen TV in the world.
As seen in the game's opening, Yooka was watching his enormous TV one day, when a bat buzzed by his head. Yooka flicked out his tongue and swallowed it. Unknown to Yooka, the "bat" was actually a metallic transmitter. Suddenly, Yooka's remote jammed and the TV went blank. A huge hand shot out of the screen and grabbed Yooka by his neck, and pulled him into the Media Dimension. The cold claw belonged to Microsoft, the overlord of the Media Dimension, who had intended to make Yooka his new mascot and conquer the world.
Yooka managed to find the hidden pagies in the strange, television worlds. Yooka made it through a disturbing cemetery, an odd cartoon land, an enormous jungle, an ancient Chinese village, the mysterious Planet X, and Rezopolis, the capital of the Media Dimension. Yooka made it into Microsoft's inner sanctum and battled them head-to-head. Using Laylee, Yooka defeated Microsoft, and made it back home in time for his shows. Microsoft transformed into a ball of energy and escaped.
Two years later, Yooka is still living in Maui and still greatly enjoys watching TV. Eventually, every day began to seem like the same one over and over again. Yooka was on the verge of insanity. One day, the TV goes blank for a few seconds, then flashes Microsoft's image over and over again.
Two Playtonic agents show up at Yooka's house, requesting his help. He denies, saying he's already saved the universe once. One of the agents then beats Yooka over the head with a bat (non-flying one), knocking him unconscious.
When he wakes up, he realizes he is in an interrogation room. The two agents ask Yooka what he knows about Microsoft, Yooka tells them everything. Once again they ask for his help, one of the agents reaches under the table and pulls out a briefcase full of pagies, as well as a secret Ice key. Yooka finally agrees to help them. The two agents give him a kinect game, and say they want Microsoft to "disappear",
As Yooka leaves the building, a beautiful female agent walks up to him, and introduces herself as "Agent Stopswopper", she wishes him good luck and leaves. Yooka then leaves to the Media Dimension.
Once Yooka is in the Media Dimension, he navigates through several channels. Toon TV; Scream TV; Rocket Channel; Circuit Central; Kung Fu Theatre; The Pre-history Channel; Rezopolis; and Channel Z. Once Yooka navigates through Rezopolis and Channel Z, he fights the overlord again. By dropping a large TV on top of him, Yooka defeats Microsoft. Microsoft once again transforms into a ball of energy, and is then trapped in the same TV Yooka dropped on him. Microsoft begs him to let him out of the TV, they even bribe him with Banjo Threeie, but Yooka shuts off the TV.
After defeating Microsoft a second time, Yooka retreats back to his mansion in Maui, which was looked after by his newly hired butler, a tortoise named Tuptip. Yooka is watching the news one day, when Agent Swopstopper contacts him through his TV. She says that Microsoft has kidnapped her, and she is trapped in Rezopolis. Yooka uses a secret entrance to the Media Dimension, that he calls the "BatCave".
Yooka navigates through all new channels. Holiday; Mystery; Ancient Egyptian; Army; Western; Pirate; Greek Mythology; Fairytale; Anime; Mafia; Superhero; and Channel Z. Once Yooka collects all the pagies, he travels to an enormous Space Station above Earth, and battles Microsoft. Unlike the previous two times, Microsoft did not transform into a ball of energy, instead he exploded into several pieces, possibly meaning that they are truly dead.
Yooka is last seen in a hotel room with Agent stopswopper, who is telling him about her time in the Media Dimension. Tuptip contacts Yooka, saying there is an emergency, however Yooka disconnects the computer and ignores him.
