Skunked!.When the Tortuga gets taken over by spotted skunks who decide to den up, the Wild Kratts team must try to reclaim their headquarters. In what turns out to be a very stinky situation, the Wild Kratts team gets sprayed one by one and are forced to try ever more elaborate plans to take back their HQ, while simultaneously searching for an effective skunk stink antidote. Meanwhile, Zach sneaks into the Tortuga to take it and all of Aviva's inventions data, and even kidnaps the skunks with his new invention. The crew learned about their defences and how they release their stench. The Kratt Brothers must use their skunk powers to stink up Zach to make him run away from the Sonoran Desert and free the skunks from the Tortuga. The Wild Kratts team then have to use Aviva's antidote to freshen them again.
