Ono alerts Beshte, Kion and Fuli about an event taking place in the Falls. When they arrive, many animals have gathered together near a tree in an orderly queue. Timon and Pumbaa explain that Bunga is giving out advice. Some animals start asking for help, and Bunga proceeds to give them terrible advice. Timon and Pumbaa quickly tell everyone to get back in line, refusing anymore freebies. An animal gives Timon a bug, and he's ready to let him in, until the Lion Guard tell him that they need to speak with Bunga. Annoyed, Timon allows them access, although Beshte is too big to fit through and instead waits outside.
They speak with Bunga, who reminds them of Rafiki's words, and that he is now the smartest and bravest animal in the Pride Lands, and that he plans on giving all the animals advice. Timon then ushers the Lion Guard out, since other animals are waiting for Bunga's advice.
Timon and Pumbaa invite Fuli back to Hakuna Matata Falls for dinner, after Bunga is proven to be immune to poison. Although they try to get her involved, Fuli winds up saving Bunga from a crocodile and soon leaves of her own accord.
The Lion Guard heads over to Hakuna Matata Falls to speak with Timon and Pumbaa. Bunga confesses to his uncles that he had failed to obtain the Utamu grubs, but Timon and Pumbaa explain that the real reason they celebrate Utamu is because of Bunga. They soon reveal that they had found the Utamu themselves, and Bunga, Timon, and Pumbaa happily eat the grubs together as the rest of the Guard watches.
The Lion Guard are first seen lounging at Hakuna Matata Falls watching Bunga dive into the water when the galagos interrupt their fun. Laini and the galagos explain that a leopard has invaded their territory. Before they can head over to the galagos' home, they hear the cry of a giraffe and race over to save him. At the very end of the episode, the Lion Guard is, once again, lounging at Hakuna Matata Falls, when Laini interrupts them again to tell them there is still someone in their tree. They leave Hakuna Matata Falls to see who it is. It turns out that it was actually Bunga, who had come back to snuggle with the galagos.
The Lion Guard have a sleepover at Hakuna Matata Falls after hearing a scary story from Rafiki about a creature known as the Zimwi. They are awoken by Young Rhino, Mtoto and Young Hare who claim that they have seen the creature for themselves. Kion refuses to believe them, so Timon and Pumbaa chime in. Timon tells them how his ma's cousin's friend knew an ox that ran into the Zimwi once, and that the ox was eaten by the Zimwi. Kion finds holes in his story, but Timon is persistent in his belief that the Zimwi truly exists. The young animals become frightened, so Kion takes the Lion Guard out into the Pride Lands to see what the Zimwi really is.
After Bunga agrees to watch over Hamu, he brings him to Hakuna Matata Falls, and teaches him how to dive into the water.
Soon, Twiga gets their attention, and Bunga notices Twiga, her daughter, Juhudi, Young Rhino and his mother, Young Serval and his mother, and Young Monkey and his mother.
Twiga asks if Bunga could watch over their children, and Bunga agrees. The mothers leave, promising to return before sunset.
Once left alone, Bunga decides to show the kids how to teke (kick), ruka (jump) and teleza (slide), and they make it into a game.
Later, Reirei's Pack observes the group as they play, and move in to confront them.
While Bunga deals with Reirei, the young animals use the techniques that Bunga showed them to defeat the other jackals.
Soon, the other members of the Guard arrive, and Kion orders the pack to leave.
Reirei agrees to do so, and she and her pack rush off.
Just then, the parents arrive to pick up their children. Bunga proudly tells them of how they bravely defended themselves against the jackals, which initially horrifies the parents.
But when they learn that Bunga taught them how to defend themselves, Muhimu declares him to be the best babysitter ever, much to Fuli's surprise. The young charges then gather around Bunga for a final embrace, as Bunga claims that he knew it all along.
With Christmas fast approaching, Timon, Pumbaa and Bunga set up a Christmas tree just outside the falls. When the rest of the Lion Guard arrive, the trio sing "Christmas in the Pride Lands" to explain more about the holiday. They are also told about Dandy Claws, a mysterious individual who leaves presents under the tree, but only when a certain song has been sung and performed under the tree on Christmas morning. Timon confesses that Dandy Claws will never visit because of that, but the Guard have to leave him to focus on their patrol.
Later, the Lion Guard decide to put on the performance, gathering up all the required items and animals needed. On Christmas morning, Bunga wakes up his uncles, but Timon continues sleeping at the bottom of the falls, not wishing to be disappointed. Bunga forces him awake, and takes him to the tree, where the animals perform "The Twelve Ways of Christmas". Although Timon and Pumbaa are overwhelmed by the performance, Bunga is disappointed that Dandy Claws never showed up. But Pumbaa grabs their attention, having dressed up as Dandy Claws to surprise Timon. Although Pumbaa forgot about the gifts, Timon is more than happy with the gifts from the performance, as well as being surrounded by friends and family. The Lion Guard decide that Christmas should be celebrated every year, and they wish each other a Merry Christmas.
