When your opponent Summons a monster(s) while you control a Toon monster: Shuffle that monster(s) into the Deck.
When an opponent's monster declares an attack targeting a face-up Level 4 or lower Toon Monster you control: You can make the attack a direct attack instead.
If you control "Toon World": Target 1 face-up monster your opponent controls; Special Summon 1 Toon monster from your hand or Deck, whose Level is less than or equal to the Level/Rank of that monster, ignoring its Summoning conditions.
When a Spell/Trap Card, or monster effect, is activated, while you control both "Toon World" and a Toon monster(s): Negate the activation, and if you do, destroy that card. You can only activate 1 "Toon Terror" per turn.
