Cannot attack the turn it is Summoned. If "Toon World" on the field is destroyed, destroy this card. While you control "Toon World" and your opponent controls no Toon monsters, this card can attack your opponent directly. If this card inflicts battle damage to your opponent: Discard 1 random card from your opponent's hand.
One of the features of toon monsters is that you can attack your opponents directly by having Toon World in the field. Toon Kingdom is better since it's treated as Toon World and it protects your toon monsters from getting destroyed.
