WILD KRATTS will have new episodes this week, followed by four more premieres during “Weird Kratts Week,” October 22-26, and a new spidery Halloween episode on October 31, at 4 p.m., Monday-Friday.

October 16, 2012 – #202 “Race for the Hippo Disc”
When Chris and Martin accidentally lose a Power Disc on the African savannah, the Wild Kratts go into crisis mode to find the disc before it gets into the hands of Zach Varmitech. Science Concept: Territoriality.

October 17, 2012 – #203 “Creature Power Challenge”
After getting caught in the middle of a tussle between a grumpy rhino and an outraged elephant, Martin and Chris decide to have a contest to decide what are stronger – elephant or rhino powers. Science Concept: Animals have adaptations for where and how they live.

October 18, 2012 – #204 “Termites vs. Tongues”
When Aviva and Koki accidentally miniaturize themselves and get carried away by termites, Martin and Chris must split up to search for them. Science Concept:Predator/prey relationship.

October 22, 2012- #129 “Seasquatch”
The Kratt brothers’ sub loses power while they are exploring the strange landscape of the ocean depths and they are trapped on the ocean floor. Aviva must figure out how to harness the energy from the deep sea’s hydrothermal vents in order to save the brothers and return them to the surface. The WILD KRATTS team learns all about the amazing process of chemosynthesis and how deep sea creatures transform toxic chemicals into energy. With a little help from the Yeti crab, Martin and Chris are able to capture the this energy and use it to restart the amphi-sub and return to the surface.Science Concepts: Chemosynthesis; how special deep sea creatures transform such toxic chemicals into energy.

October 23, 2012 – #133 “Gecko Effect”
There’s a mystery to be solved, as the WILD KRATTS team wonders how a Gecko lizard climbs up smooth surfaces and can even climb upside down. The gang uses the Miniaturizer to shrink and discover it’s all about physics. But in the meantime, Zach has stolen their Miniaturizer and now imprisons them in a glass terrarium. Martin and Chris activate the new Gecko Powers of their Creature Power Suits and must retrieve the Miniaturizer before Zach shrinks all the animals in the creature world. Science Concept: Physics – Objects have electrical charges that attract one another. The gecko’s toe pad structure enhances these charges so much that they can “stick to” smooth surfaces.

October 24, 2012 – #139 “Googly Eye”
The Kratt brothers secretly “borrow” Aviva’s half-finished night vision goggles to go in search of a mysterious nocturnal creature. But when the unstable goggles stop working, the brothers find themselves taken in by the nocturnal society of the tarsier. Then, when the tarsier troop is in danger of losing one of their own, Chris and Martin must tap into their newfound understanding of nocturnal living and help the troubled tarsier family. Science Concept: Nocturnal-vision creatures are creatures that come out at night. Eyes help a creature see by collecting the light that comes from objects all around. They have a feature called an iris that opens or closes the pupil to let more or less light in.

October 25, 2012 – #135 “Quillber”
It’s Aviva’s birthday, and Chris and Martin decide to collect shed porcupine quills to make a beautiful necklace as a gift. As they tag along with an African crested porcupine, they discover that animals have different ways to defend themselves from predators, one of which comes in handy to protect the porcupines from Zach’s latest animal collection scheme. Science Concept: Defense strategies; animals have different ways to defend themselves from predators. Some animals, like porcupines, have highly specialized features designed to ward off predators. Porcupine quills are modified hairs, designed by nature into a deadly defense.

October 31, 2012 – #208 “Spiders”
When the creature adventuring Kratt Brothers take a nasty tumble, the WILD KRATTS team sets off on a mission to find and recreate one of the greatest of all biotech engineering secrets: spider silk. Science Concept: Biotechnology – Humans can develop new objects by taking cues from nature.

WILD KRATTS also just launched Creaturepedia, an online animal encyclopedia that includes information on each animal’s creature powers, diet, geographic location and more, as well as video content, available on PBSKIDS.org/wildkratts.
