From the The Hunted release notes

Leap Frog equipment will trigger when an opponent plays or activates an attack reaction. When the triggered effect resolves, you may add the equipment to the active chain link as a defending card.
If this card is already defending on a previous chain link, this may be added as a defending card to the active chain link as a defending card (moving it from the previous chain link to the active chain link).
If this card is already defending on the active chain link, it cannot defend again on the same chain link.
If an effect prevents you from adding an equipment to the active chain link, the Leap Frog equipment will not be added when the triggered effect resolves.
