"Neck and Neck" is the sixth episode of the second season of Wild Kratts, originally airing on PBS Kids on January 18, 2013. Overall, it is the 46th episode of the series. The episode was written and directed by Chris Kratt.
In this episode, while Chris and Martin search for the answer to why giraffes have long necks, a mischievous giraffe begins secretly taking Creature Power Suit parts and supplies from the Tortuga.
The episode begins with a live action segment. While the Kratt brothers are packing their gear, a giraffe pokes its head through the window. Outside, they find a few more giraffes, and afterwards, they ask their "What if?" question and "transform into their animated selves".
The Kratt brothers introduce the giraffe to Aviva after one wakes Chris up while he was sleeping in his hammock. Aviva begins to wonder why giraffes have long necks, and begins a conversation with Koki, who has finished building a retractable window for the Tortuga. She says to her that she thinks giraffes have longs necks because long necks allow them to reach leaves high up in the trees. Koki strongly disagrees, saying that giraffes use their necks in fights with each other. They then decide to settle the dispute by asking what the Kratt brothers think. The Kratt brothers have no idea how to answer the question, so Chris decides on an experiment to find out. For the whole time this was going on, a giraffe stuck its head through the new retractable window and takes a roll of tubing.
The Kratt brothers find a giraffe, which Martin names Necktie, and send a scan of its neck to Aviva, who uses the information gathered to create a Giraffe Power Disc. While she was doing so, the same giraffe that poked in before takes a critical component – the deactivation module, out of Martin's Creature Power Suit. Afterwards, Jimmy quickly teleports the Suits to the Kratt brothers, who follow Necktie to a mixed herd of herbivores. Chris activates as a zebra, and Martin activates as a giraffe. After a lion attacks Necktie, the Kratt brothers decide to deactivate their Creature Power Suits. Chris successfully does, but Martin is unable to. Aviva realizes that she lost Martin's Suit's deactivation module, but she says she has the plans and can make another one. Again, while nobody was looking, the same giraffe that took the deactivation module takes the plans.
The Kratt brothers decide to continue the experiment by first finding a place with undisturbed trees. Jimmy tells the Kratt brothers that he knows of such a place that he fenced off a while ago, and sends them the coordinates. As for Martin's dilemma, Aviva resorts to using the deactivation module in Chris's Suit. Koki takes Jimmy to the site, where Chris and Martin are waiting. Chris breaks the fence surrounding the area. Not long after, several herbivores arrive. After Koki and Jimmy leave with Chris's Suit, a giraffe challenges Necktie for his female. At first, the giraffe beats him, but Necktie repeatedly retaliates with attacks from his neck. After the final blow, Chris realizes that Necktie has the longer neck, and he thinks that might benefit giraffes in fights, supporting Koki's proposition. The Kratt brothers also realize that giraffes are the only herbivores that can reach the leaves high up in the trees, supporting Aviva's proposition. They call the rest of the crew to tell them the good news, but all Aviva could say was that Chris's Suit disappeared and that Martin "might be in giraffe mode forever". At first, hope is finally lost for Martin, until the Kratt brothers see a giraffe with everything that their team previously lost. They follow it into a thicket, and Martin calls out its name as Necklace. When they follow Necklace out of the ticket, they find her with Necktie. Necktie hits Martin a few times, which convinces Necklace that he is stronger than Martin. While the two giraffes embrace, Martin picks off all their stuff off of Necklace's neck. At the end, Aviva inserts the deactivation module back into Martin's Suit, and after concluding that long necks benefit giraffes in more than one way, the Kratt brothers, both with Giraffe Powers, and the rest of the Wild Kratts play soccer.
The show transitions into the ending live action segment. The Kratt brothers climb up a tree to feed and to get a closer look a giraffes. Afterwards, the Kratt brothers conclude the episode by saying "Keep on creature adventuring; we'll see you on the creature trail!"
