List of episodes


Master Yo needs to retrieve the Toilet Brush of Illumination from the safety deposit box dimension, which opens only once every hundred years. The Night Master, knowing this, orders Yuck to hide inside Yo's body until he has the brush, and then take it. Now Yin and Yang need to stop Yuck with hazards in the form of Yo's insides trying to slwo them down!


Woo Foo Weapons Introduced

  • Toilet Brush of Illumination


  • This episode features Yuck as the main antagonist.
  • This episode also features the Night Master as a secondary antagonist.
  • The episode title is an apparent parody of Jules Verne's classic 1864 sci-fi novel, A Journey to the Center of the Earth.
  • On another interesting note, the font used for the title is somewhat similar to that used in the film adaptations of Spider-Man.
