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 their Miniaturizer to shrink down and discover it's all about physics: all objects have electrical charges that attract one another and the gecko's marvelous toe pad structure charges so much that they can walk on surfaces as smooth as glass. 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.
