Card Trivia:Toon World
- This is one of the cover cards of Structure Deck: Pegasus and the box of Duelist Legacy Volume.1.
- This book appears in the artworks of "Shadow Toon", "Shine Palace", "Toon Bookmark", "Toon Dark Magician", "Toon Dark Magician Girl", "Toon Defense", "Toon Page-Flip", "Toon Table of Contents", "Toon Terror", and "Twister".
- In this card's first OCG/TCG artwork, "Manga Ryu-Ran" appears on the front cover and "Toon Mermaid" appears on the back cover, and the book is open to "Fiend Castle".
- Also, this card's OCG/TCG artwork is also taken from Yu-Gi-Oh! Duel 127 (Duelist Duel 68): "Do the Impossible!", specifically from the panel showing "Toon Summoned Skull" for the first time while "Toon World" is open to "Evil Castle" and "Toon Mermaid" and "Manga Ryu-Ran" were hidden inside the book, causing them to be visible on its covers.
- This book is based on a pop-up book, a book with three-dimensional pages and elements that "pop up" when a page is turned.
- This card has an improved counterpart: "Toon Kingdom".
- This card also has a Skill Card counterpart: "It's a Toon World!"
- In the first Japanese print of this card, the player must pay 500 Life Points during each of their Standby Phases to keep "Toon World" in play, and if "Toon World" is sent from the field to the Graveyard, they gain all Life Points paid for the maintenance of "Toon World".
- The video games Yu-Gi-Oh! Duel Monsters 5: Expert 1, Yu-Gi-Oh! Duel Monsters 6: Expert 2 and Yu-Gi-Oh! The Eternal Duelist Soul use the old effect.
- In Yu-Gi-Oh! The Eternal Duelist Soul, "Toon World" has the original effect, despite having text for the newer effect.
- In Yu-Gi-Oh! Worldwide Edition: Stairway to the Destined Duel, "Toon World" has the newer effect, despite having text for the older effect, when played in Japanese. Other language settings use the text for the correct effect.
- In the video game Yu-Gi-Oh! The Duelists of the Roses, this card's two artworks were featured on two different cards:
- The Structure Deck: Pegasus artwork of this card was featured on the Field Spell Card "Toon World".
- This card's first OCG/TCG artwork is used for the Equip Spell Card "Fiend Castle".
- In Yu-Gi-Oh! Duel 110 (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.
