"A Huge Orange Problem" is the 28th episode of the first season of Wild Kratts, originally airing on PBS Kids on June 4, 2012. The episode was written and directed by Martin Kratt.
In this episode, while the Kratt brothers are off searching for orangutans, Aviva, Koki and Jimmy Z get sore arms after getting carried away swinging on vines. The brothers attempt to rush back with the first-aid kit but a male orangutan keeps tossing them back into the forest. Meanwhile, Zach Varmitech sends his Zachbots to cut down the trees of the Bornean rainforest so he can find black wood to build a side table.
The episode begins with a live action segment, which shows the Kratt brothers hanging out with some olive baboons. Afterwards, they ask their "What if?" question and "transform into their animated selves".
The Kratt brothers head off to meet orangutans in the Bornean tropical rainforest, but not after Aviva hands them the first-aid kit. Aviva then looks up at the trees and sees Koki and Jimmy swinging on vines to grab and eat figs, prompting Aviva to join. Not far away from the Kratt brothers', Zach Varmitech is traveling in his jet. When he sets his v-shaped glass down, it falls to the floor and shatters, convincing him that he needs a side table, and orders his Zachbots to prepare to find some black wood so he can craft one.
The Tortuga crew feels sore after swinging on vines for too long. Aviva calls the Kratt brothers, complaining that she, Koki, and Jimmy need a specific medicine in the kit to relieve their sores. The Kratt brothers head back to the Tortuga, when an orangutan grabs Chris by his head. It tosses Chris, and then Martin, to an orangutan mom and baby. Aviva calls again, demanding that they return to the Tortuga. The Kratt brothers head back, but the same orangutan grabs them by its feet and tosses them back to the same location. After Aviva calls them a third time, Martin decides to name the orangutan that tossed them back Huge-O. While trying to sneak back to the Tortuga, Huge-O tosses them to the exact same location, where they see the mother orangutan mash some leaves inside her mouth. She pours the liquid out and rubs it on the arms of the baby, relieving its sore arms. With this information, they grab some leaves and start heading back, but unknowingly lose the first-aid kit. Fortunately for them, Huge-O allows them to pass after seeing the piles of leaves in their hands.
The Kratt brothers arrive at the Tortuga. Chris crushes the leaves with a leaf press, and the crew rubs the liquid on their skin, eventually relieving them of their soreness. Not long after, the Wild Kratts hear the sounds of Zachbots using their saw arms to cut trees down. Aviva tosses Orangutan Discs to the Kratt brothers, and they bump into Huge-O. The brothers touch his hands and activate their Creature Power Suits. Huge-O and the Kratt brothers bash and wreck several Zachbots. Zach, frustrated, gets out a saw, but Huge-O grabs him and tosses Zach onto a branch in a nearby river. Afterwards, the Wild Kratts summarize what they have found out about orangutans.
The show transitions into the ending live action segment. The Kratt brothers teach the olive baboons that mint leaves are good to eat, so good, that they take some that was supposed to be for their own mint tea. The Kratt brothers also mention a time when they taught orphan orangutans how to eat some things. They conclude the episode by saying "Keep on creature adventuring; we'll see you on the creature trail!"
