Up and at 'em is a medium difficulty stamp in Club Penguin. In order to obtain this stamp, the player has to be revived by another ninja in Card-Jitsu Snow, and still complete all three rounds (and optionally a bonus round). If a snow ninja uses a power card to revive the player, this stamp will not be earned, unless the player was revived normally afterwards. Using the revival card available to members will also not count towards this stamp.
This stamp was released on May 23rd, 2013, along with other Card-Jitsu Snow stamps.
This stamp is a bait item if a player attempts to perm it.
