The history of Jollywood is explained in the episode "The Rock of Sages". The area was unsettled and devoid of color until, one day, a group of dwarfs known as the Seven Sages met with seven colored gems. By accident, each of the seven gems formed the magical, yet powerful Rock of Sages. Together, the Seven Sages then used the combined gem to bring magic and color to the land. Later, creatures and more dwarfs arrive and a new kingdom is founded: Jollywood.
Later on, an evil wizard known as Lord Grudgemunger snatched the Rock of Sages from the Seven Sages and used it to rob the kingdom of its color and magic. The dwarfs, however, retrieve the gem and restored Jollywood to her beauty. Knowing how the gem is so important to the kingdom, the Seven Sages broke up the gem back to its seven components and hide them in the seven corners of the land so it won't be found by Grudgemunger once again.
