Tribe Mamanuca is the merged tribe formed in Episode 10 of Extinction Island Season 1, created when Tribes Vanua and Kadavu were combined by host announcement on Day 19. The tribe name Mamanuca was revealed at the merge, with new buffs distributed to all five members on the neutral beach.
The tribe immediately faced Tribe Yasawa in the Wipeout immunity challenge and lost, sending them to their first Tribal Council as a new unit. Despite only hours of existing together, the three former Vanua members — Priya Nair, Colton Briggs, and Denise Fuentes — moved quickly to bring Kadavu's Nadine Kowalski onside, resulting in a 3–2 vote against Denise, who had been seen as the swing vote threat.
From Vanua: Priya · Colton · Denise
