The box is lit, so the player must have a bunny in the circle.
The pink box is a rectangular box in the bottom left corner of the art box on many cards in various Killer Bunnies games. If this box is "lit," that is, if it is colored pink, the card is considered aggressive and cannot be played unless the player has a bunny in the Bunny Circle. The exception is Choose a Carrot cards, which are not aggressive, but nonetheless require a bunny in the Bunny Circle to be played. If the card may be played regardless of whether the player has a bunny in the Bunny Circle, the box is left blank.
Pink Box With a Circle[]
In some games, cards can display a pink box with a pink circle superimposed. These cards require the player to control a bunny in the Bunny Circle at all times while the card is saved. If at any point the player has no bunnies, the saved card is immediately discarded.
Pink Box in Other Killer Bunnies Games[]
This card can be played at any time.
In KinderBunnies: Their First Adventure!, the pink box is replaced by a pink star that functions in the same way.
In addition to the pink box, cards in The Ultimate Odyssey and Heroes vs. Villains can also have a green rectangular box. If the green rectangle is lit, the card may be played only if the player controls a city in the City Circle. Similarly, cards with an orange or black rectangle can only be played if the player has a Psychic Penguin or alien down, respectively.
