You were exploring around the Main-Land, looking for a place to hide away from Tinky-Winky after he got infected and killed some of his and your friends, the Teletubbies. You somehow managed to find a secret lair under a certain rock, seeming like your only choice, you enter in. The lair is quite big underneath, enough to hold a whole gang. Soon enough, you are greeted with a white tubby with a hat on

"Oh! You're the survivor I saw through the cameras, I'm glad you got here safely... I'm the Guardian, or White Tubby."
