Janja, Cheezi, and Chungu have found a groove filled with Tikiti Melons, melons that are filled with water. They try to steal them but the Lion Guard shows up and stops them. The Guard then stays to guard the Melons. The Hyena trio head back to the Outlands Volcano and tell Scar. After hearing about the Melons, Scar orders the Hyenas to go back and steal all of them as this will leave Ma Tempo's Herd easy prey for Janja's Clan due to dehydration. When Janja expresses fear of the Lion Guard, Ushari suggests a lizard friend of his named Kenge. Janja scoffs at the idea of a "little lizard" helping them defeat the Lion Guard. Ushari tells them Kenge is a big and bad lizard and to not call him a little lizard "whatever you do".
Janja, Cheezi, and Chungu go back to the Pride Lands and meet up with Kenge who they discover is a big and ferocious moniter lizard who hates even hearing the word little. Kenge causes a comotion that leads the Lion Guard to him. A fight breaks out where Kenge bites Kion, Fuli, and Besthe and renders all three of them unable to use their legs. After Kenge leaves, Ono realizes what Kenge is and reveals that moniter lizards have venom in their teeth that induces paralisis. Ono goes to get Rafiki but finds Makini and brings her to the Guard. As Makini treats the venom, Ono spots Kenge with the Hyenas, who are stealing Takiti Melons again. Realizing what's going on, Kion sends Ono and Bunga to stop them. Ono and Bunga try to do so but Kenge bites them too and leaves with the hyenas.
Ono can't fly anymore but Bunga is discovered to be immune. Bunga and Makini go to save the Melons. As Makini saves the Melons, Bunga provokes Kenge into biting the Hyenas by calling him a little lizard. The rest of the Lion Guard shows up and Kion blasts them back to the Outlands.
