Over the Big Balls To Nana’s House We Go is the first episode and season premiere of season 4 of Wipeout, as well as the first episode of Winter Wipeout in season 4.
Starting from season 4 onward, the Wipeout Zone was consisted of three finalists instead of four. However, the Wipeout Zone would later revert back to four finalists in season 7.
For the first time in Wipeout, the season was split into seasonal Wipeout episodes. Episodes 1-8 of the fourth season are Winter Wipeout episodes, Episodes 9-15 are Spring Wipeout episodes, and Episodes 16-31 are Summer Wipeout episodes. This pattern continued into season 5 of Wipeout, though only Winter & Summer Wipeout episodes were hosted.
