Once Upon a Time fans will get their first glimpse of Ariel (JoAnna Garcia Swisher) on the next episode of the ABC fantasy series.

Viewers will be introduced to Ariel the mermaid in Sunday's episode, appropriately titled Ariel. According to the ABC press release, the episode will consist of a flashback to the Fairy Tale Land That Was featuring Ariel and Snow White (Ginnifer Goodwin).

Ariel saves Snow from drowning, and Snow expresses her gratitude by introducing her to Prince Eric (Gil McKinney). Ariel will gradually fall in love with Prince Eric, as most fans of the classic fairy tale know.

In the present, Snow, Emma (Jennifer Morrison), David (Josh Dallas) and Hook (Colin O'Donoghue) go on a mission to save Neal (Michael Raymond-James), who has become imprisoned by Peter Pan (Robbie Kay).

Meanwhile, Regina (Lana Parrilla) and Mr. Gold (Robert Carlyle) will try to find a way to defeat Pan once and for all.

ABC also released new promotional photos for the episode featuring Ariel and Snow smiling and enjoying each other's company. View the photos here.

The characters have spent a lot of time in Neverland and will continue to be there for the remainder of the episodes airing in 2013. They will go back to Storybrooke for the spring 2014 episodes, but Dallas revealed to TV Guide recently that a little bit of Neverland might be coming back with them.

"The island may end up coming home with us in some way," the actor teased. It is not clear whether he means some of the island itself or some of its curses, so viewers will have to tune in and find out.

Once Upon a Time airs Sundays at 8 p.m. on ABC.
