In Yu-Gi-Oh! Duelist Duel 51: "Toons Attack!", Yugi Mutou speculates that since this card isn't circulated to the general public, it seems to be an original card made just for Pegasus, being the only one in the world.
According to Pegasus, the page the "Toon World" book is open to is called "Evil Castle", and is the lair of "Toon Summoned Skull".
This is one of two Spell Cards in the game with no effect, this one with only a cost. The other card is “Broken Bamboo Sword”. Both cards don’t do anything and are only meant to support other cards and activate their effects.
