In this challenge, the islanders are divided into 2 teams based on gender, with the boys being the stags and the girls being the hens as a part of the challenge's wedding-theme. The challenge consisted of 2 different parts, with the first part featuring the members of each team having to pour giant cups of water over them, before then having to try and perfectly flip the cup upside down on the table. The team that managed to flip over all of their cups the quickest would win the first part of the challenge.
The second and final part of the challenge, acts as a relay race, consisting of three different tasks. In the first of these tasks, every member in the team is tied up to one another and they have to try and undo the knots as quick as possible to try and get ahead of their opponents. The second stage, features a ring-toss game, where members have to try and toss wedding rings onto a giant finger. Once they've managed to get all their rings on the finger, they'd be able to move onto the final part, where the 3 selected team-members would have to each down a pint. The team that manages to complete all of these first would win the challenge overall. The reward for the winning team here, would be to receive a new islander of the opposite sex, in the form of either AJ for the boys or Danny for the girls.
