Radical Land is the original home of King Radical and Ron Wizard.  It is a place filled with incredible creatures such as Helicopter Ents and anthropomorphic rainbow unicorns, a land in which the rivers are filled with Mountain Dew.

However, since the war against Sparklelord, the land has began to fall into corruption.  King Radical plans to transfer it's inhabitants to McNinja's Earth, which will become the new Radical Land.

Racism no longer exists in the Radical land.

It is believed that many of the more awesome aspects of McNinja's world come from it's proximity to Radical Land, although its effect is countered by a far more boring world that is also nearby (in spacetime, or whatever seperates these universes).
