Kalle Videkull, aka Happy, aka Yazzo, aka Frostbeule is primarily a SMK Non-NBT player when it comes to karting. He has also played MKWii and held many WRs, being the first person to sub 1'10 on Luigi Circuit and holding that World Record for over 2 months now. He is a very talented player in many racing games, including F-Zero, and Trackmania where he once won $10 billion in a tournament.
Many strive to figure out Happy's true identity. People continually nag him to submit a real photo of himself. Instead of posting his real photo he continues to post photos of old men holding camera's little long haired teenage boys.
Happy plans to give half of the 10 billion dollars he won to Mark Jones to support the Mario Kart website.
