Justin, Katie, and Sadie

The Katie+Sadie-Justin Attraction is the one-sided relationship (on Katie and Sadie's side) and conflict (on Justin's side). The relationship, and conflict, was mostly seen in Total Drama, Drama, Drama, Drama Island, as it was not worked out in the second season due to the fact that Katie and Sadie did not qualify for Total Drama Action.

Not So Happy Campers - Part 1
Once Justin arrived at Camp Wawanakwa, Katie and Sadie stared at him in awe, like the rest of the girls. Sadie even fainted in his presence.

Total Drama, Drama, Drama, Drama Island
Katie and Sadie formed a team with Justin in order to search for the million dollar case. At first Justin enjoys the attention the girls are giving him, and begins telling them about his modeling career. In the confessional, the girls say that Justin is "so yummy!". However, Justin eventually tires of the duo's nonstop talking, and ends up ditching both Katie and Sadie by tricking them into spending the remainder of the competition in a cave. Even though Justin hates them, Katie and Sadie both have crushes on Justin and believe that he likes them back. They even get into an argument over who he likes better during their stay in the cave. In addition, the two girls seem to think everything of his essence must be beautiful, and theorize that Justin never needs to use the bathroom.

Celebrity Manhunt's Total Drama Action Reunion Special
When Justin said he was going to "be just another pretty face", Katie and Sadie (along with Owen) say he has pretty abs, pecs, and butt. The three would later join Trent, Beth, Geoff and Eva into finding some help only to learn that the seven of them would not be returning for Total Drama World Tour.

Theme Song
Katie and Sadie are seen gushing at Justin in the theme song while he looks in his mirror.

Haute Camp-ture
Sadie and Katie are gushing over Justin (while he is diving of the diving board at Playa Des Losers), and saying how cute he is, much to the annoyance of Noah.

Trivia

 * This attraction appears to be the Total Drama Island counterpart of the Katie+Sadie-Trent Attraction, as both attractions are one-sided on Katie and Sadie's part and Katie and Sadie fight over the male.
 * Justin was the only one of them to qualify for Total Drama Action. None of them qualified for Total Drama World Tour.
 * Sadie and Katie are the only one in the attraction to compete in only one season.
 * It may possibly be because of this attraction that Katie and Sadie did not qualify for Total Drama World Tour. In the Celebrity Manhunt's Total Drama Action Reunion Special, Justin was the first person to volunteer to go with Geoff in search of rescue. Instantly after he said this, Katie and Sadie both eagerly volunteered as well, implying that they did so just to be with Justin.
