Cha-Cha (Japanese チャチャ) is a young Shakalaka that had ventured away from home.
He describes himself as a "proud wandering lone-wolf cha-champion of the great Shakalaka Tribe".
Cha-Cha is a lost child from a Shakalaka tribe within the Deserted Island. He, along with Kayamba, were searching for a legendary mask to bring back to their tribe for a special ritual that young Shakalaka participate in. As Cha-Cha began to claim the mask, Kayamba fought with him over the mask and mistakenly dropped it into an Aptonoth stampede. This lead to the mask being stuck in the crest of one of the Aptonoth, which caused both Cha-Cha and Kayamba to chase after the mask. Though they rode Jaggi and Aptonoth to try to get the mask back, a Rathalos captured the Aptonoth holding the mask and flew off with it, along with the two young Shakalaka riding on the creature. Kayamba fell off the Aptonoth immediately, after the Rathalos captured it, while Cha-Cha ended up falling into a Jaggi nest. Not to long after falling from the sky, an unnamed hunter discovered him and saved him from packs of predators. This hunter brought him back to Moga Village, where he and Kayamba now call home. While in Moga Village, he helped his hunter defeat many monsters in battle such as Duramboros, Ceadeus, Ivory Lagiacrus, and even Alatreon. When not in Moga Village, him and Kayamba are known to look for legendary masks in certain lands.
