When the Lion Guard stumbles across Mapema Rock, Bunga resolves to hunt for Utamu grubs. Before he can start, the group is called away on another mission, but afterward, Kion agrees to help him find the grubs with Beshte and Ono. At first, the group appears to get lost in their search, but Bunga instructs his friends to follow a group of dung beetles.
While following the dung beetles, Bunga tells his friends about the day he'd met his uncles, Timon and Pumbaa. Long ago, when he'd just been a young honey badger, he'd encountered Timon and Pumbaa singing "Utamu". Instantly smitten, Bunga had begun following them around until Timon had instructed him to climb a tree and fetch them some Utamu grubs. When Bunga had succeeded and given the grubs to Timon, the meerkat had allowed him to stay, and the three have lived together ever since.
After the story, Bunga attempts to climb a long-dead tree to fetch some Utamu for his uncles, but the branch breaks due to the decay, and the Utamu fall into the river below. Heartbroken, Bunga returns to his uncles and admits that he's failed to catch any Utamu. Timon gently reminds the honey badger that they celebrate not because of the Utamu, but because of their relationship with Bunga. They then reveal that Utamu grubs had "fallen out of the sky", and the group shares in a feast of grubs.
