When your opponent activates a monster effect, or Spell/Trap Card, that targets a "Frightfur" monster(s) you control: Negate the activation, and if you do, destroy it, then you can apply this effect.
- Send 1 of those targeted "Frightfur" monsters to the Graveyard, and if you do, Special Summon 1 Level 8 or higher "Frightfur" Fusion Monster from your Extra Deck, but banish it during your next End Phase. (This Special Summon is treated as a Fusion Summon.)
