"Mosquito Dragon" is the fourth episode of the third season of Wild Kratts, originally airing on PBS Kids on July 25, 2014.[1] Overall, it is the 70th episode of the series. The episode was written and directed by Chris Kratt.

In this episode, after they get bitten by mosquitoes, the Wild Kratts decide to find out the reason why mosquitoes suck blood. Meanwhile, Zach Varmitech comes up with another villainous plan, this time by using "Mosquito-bots" to hack into the Tortuga's main computers.


The episode begins with a live action segment. The Kratt brothers travel around the cypress swamps while talking about mosquitoes. Afterwards, they ask their "What if?" question and the show transitions into the cartoon segment.

The Wild Kratts are traveling across a river in the cypress swamps of Florida, when they all get stung by mosquitoes. Chris stops the hovercraft and Martin begins digging through his backpack to find mosquito repellant. However, the other Wild Kratts members are too desperate to wait for Martin to dig past the seemingly endless stream of junk coming out of his backpack, so they return to the Tortuga HQ. This incident inspires the Kratt brothers to find out why mosquitoes suck blood. Meanwhile, Zach Varmitech attempts to hack into the computers of the Tortuga, when a mosquito bites him. Knowing that mosquitoes steal blood, Zach gets the idea to make mosquito-inspired robots to steal data stored on the Tortuga's computers.

The Kratt brothers miniaturize and enter the water, where they find mosquito larvae floating on the surface and eating algae. They call Aviva, and tell her that blood does not play a role in the mosquito's larva stage. Then a mysterious creature swoops past them, eats a mosquito larva, and disappears into the water. Meanwhile, Aviva finds out that the female mosquitoes are the ones that drink blood (male mosquitoes drink plant sap). Aviva gets into the hovercraft and chases a mosquito that recently drank blood. She bumps into Martin, who rides along with her. Chris, now alone, gets cornered up a branch by the "swamp monster".

Aviva launches Martin up into the air so he can ride the mosquito, but he instead falls into a puddle in a cardinal plant. The mosquito then starts laying eggs on the surface of the puddle. Martin scans the back of its abdomen and finds out that the blood the mosquito drank is used to make eggs – the reason why mosquitoes suck blood.

Chris finds out the swamp monster is a dragonfly nymph after a dragonfly emerges from its body. Up in the sky, the Kratt brothers see Zach Varmitech's swarm of "Mosquito-bots" flying towards the Tortuga. Martin calls Koki and Jimmy, and Jimmy starts the Tortuga and flies it away from the swarm. Chris rides the dragonfly as it flies and simultaneously names it Swamp Dragon, who starts eating Mosquito-bots as if they were real mosquitoes. Martin activates his Dragonfly Creature Power Suit to aid Chris in taking down the swarm. About the time the Mosquito-bot swarm completely surrounds the Tortuga, Zach arrives in his jet. In spite of the success of his Mosquito-bots, the mosquito-bots are programmed to sense warm air emitted from aircraft engines, and because the engines of Zach's jet are "hotter" than that of the Tortuga's, the mosquito-bots stop following the Tortuga and instead follow Zach's jet. At the end, the Wild Kratts summarize their adventure as they resume traveling down the river by hovercraft.

The show transitions into the concluding live action segment. The Kratt brothers use nets to sift through the bottom of a creek, taking a close look at the creatures that they have gathered. Afterwards, they conclude the episode by saying "Keep on creature adventuring; we'll see you on the creature trail!"
