Toon Summoned Skull
Cannot be Normal Summoned/Set. Cannot be Special Summoned unless you control "Toon World". Must first be Special Summoned (from your hand) by Tributing the same number of monsters needed for a Tribute Summon (normally 1). This card cannot attack the turn it is Special Summoned. You must pay 500 Life Points to declare an attack with this monster. If "Toon World" on the field is destroyed, destroy this card. This card can attack your opponent directly, unless they control a Toon Monster. If they do control one, this card must target a Toon Monster for its attacks.
Highlighted part states that when Toon World is destroyed, the toon goes with it. Toon Kingdom is treated as Toon World.
When you activate this card, remove from play the top 5 cards of your Deck. This face-up card's name is treated as "Toon World". If a "Toon" monster you control would be destroyed by battle, you can banish the top card of your Deck instead.
