During her time in "Total Drama: Return to the Island", Ashleigh is placed on the Mutant Bass. She befriends mostly all of her peers, particularly Vanessa, earning a reputation as one of the friendliest cast members. She establishes a relationship with Tyra and the two remain together for the duration of the series. Later, Ashleigh also forms an alliance with Laurie and Vanessa to vote off Ryan. Her stretch in the competition comes to an end when Alex wins the opportunity to eliminate another contestant and accidentally selects Ashleigh. Ashleigh is last seen in "This Ain't The End" celebrating with the other contestants after Vanessa wins the season.
