In episode 27, Maximillion Pegasus uses this card during his Duel against Seto Kaiba. After this card is activated, it becomes treated as "Toon World" and increases the ATK of all LIGHT monsters Pegasus controls by 500. This makes the ATK of "Blue-Eyes Toon Dragon" 3500. Activating this card, also changed the background that "Toon World" was showing when it opened (it was changed from the dark castle with gravestones in the artwork of "Toon World" to the palace shown in this card's artwork). "Blue-Eyes Toon Dragon" then attacks "Blue-Eyes White Dragon", but Kaiba activates "Negate Attack" to negate the attack made by Pegasus's monster and end the Battle Phase. This card remained on the field until the Duel was over.
In episode 39, this card can be seen in the scattered remains of Pegasus' deck after Pegasus loses to Yami Yugi.
In episode 49, this card appears within a series of flashbacks that Yami Yugi had when Joey Wheeler reminded him that he is fighting for all the Duelists that had fought him with all they had.
