This is a toolassisted speedrun. For more information, see http://tasvideos.org/2568M.html. TAS originally published on 20140404.
In the sequel to Super Monkey Ball (http://tasvideos.org/2567M.html), you must once again guide a monkey trapped inside a plastic ball to the goal in each stage by tilting the game world. New features include mechanics like portals and more complex level designs, which in a speedrun, lead to some really interesting routes.
In this TAS, the authors skip all the easy levels and warp to the Expert stages, where they proceed to tear through all 50 levels as well as the 10 Master and 10 Master Extra stages, breaking many of the heavily optimized console world record times.
