Little Mermaid Jr Cast of Characters

The Little Mermaid Jr cast list includes strong lead roles, comedic featured characters, memorable villains, and flexible ensemble opportunities both under the sea and in Prince Eric’s palace. This show works especially well for schools with confident singers, expressive actors, and students who can bring color, movement, and personality to a magical underwater world.

Quick Casting Insight: Little Mermaid Jr works best when you have a strong Ariel, a charming Prince Eric, a vocally confident Sebastian, a bold Ursula, and an ensemble that can create the worlds of the sea, palace, ship, lagoon, and underwater court.

Ariel
Ariel, the heroine of our story, is a little mermaid who longs to be human. Cast a strong singer and dynamic performer in this role. Ariel has some beautiful solos but must be able to convey meaning through gesture once she loses her voice.
Gender: Female | Vocal range: Bb3–Eb5

Prince Eric
Prince Eric is the adventurous prince who captures Ariel's heart. Look for a charming performer with a sensitive nature. Prince Eric has a few small solos, but it is more important to cast a strong actor in this role.
Gender: Male | Vocal range: B3–D5

Sebastian
Sebastian is the meticulous and anxious crab who tries to keep Ariel safe while getting to lead some of the most memorable songs in the show. Look for a strong singer who can also handle Sebastian's emotional range. Sebastian can be played by a boy or girl.
Gender: Any | Vocal range: A3–D5

Flounder
Flounder is Ariel's sincere and sensitive best friend who is loyal to the end. This spunky fish also has a show-stopping solo in “She's in Love.” Flounder can be cast with a girl or a boy with an unchanged voice. This may be a wonderful role for a younger performer who is ready to take the next step into the spotlight.
Gender: Any | Vocal range: G3–Db5

King Triton
King Triton rules the sea and is a force to be reckoned with. This non-singer needs to command the stage as a strong leader but also show the tenderness of a parent. Cast a mature performer who feels comfortable playing father to Ariel and the Mersisters.
Gender: Male

Mersisters
The Mersisters, Aquata, Andrina, Arista, Atina, Adella, and Allana, are Ariel's siblings and full of personality and sass. These are great roles to showcase talented singers and dancers who can create and play six distinctive characters.
Gender: Female | Vocal range: G3–G5

Ursula
Ursula is the manipulative sea witch who tries to overthrow King Triton. She is cunning and devious and will stop at nothing to get what she wants. Cast a mature performer who can bring out this villain's humor while finding texture in Ursula's complexity. Ursula's songs can be challenging, so look for a singer who will feel comfortable with these solos.
Gender: Female | Vocal range: F3–C#5

Tentacles
The Tentacles are extensions of Ursula, perhaps the poor unfortunate souls who are now trapped in her lair. Look for six or eight performers who work well together and can move as a unit.
Gender: Any | Vocal range: C4–C#5

Flotsam
Flotsam and Jetsam are Ursula's slippery spies. These electric eels are sinister and sneaky, so look for performers who can be underhanded and devious while still being heard on stage. Flotsam and Jetsam can be played by boys or girls.
Gender: Any | Vocal range: C4–C#5

Jetsam
Flotsam and Jetsam are Ursula's slippery spies. These electric eels are sinister and sneaky, so look for performers who can be underhanded and devious while still being heard on stage. Flotsam and Jetsam can be played by boys or girls.
Gender: Any | Vocal range: C4–C#5

Scuttle
Scuttle is the know-it-all seagull who serves as Ariel's expert on humans. He is funny and off-beat. While a good singer will rock “Human Stuff,” this song can easily be spoken in rhythm. Look for a performer with good comedic timing who is willing to have fun with Scuttle's eccentricities.
Gender: Any | Vocal range: B3–E5

Gulls
The Gulls are Scuttle's flock of zany backup singers who help explain human stuff to Ariel. While there are three principal gulls written in the score, feel free to add as many as you need to best serve your production. The Gulls' solos can be spoken if necessary.
Gender: Any | Vocal range: B3–G5

Grimsby
Grimsby is Prince Eric's prim and proper valet. He is rigid in personality and constantly trying to guide Prince Eric towards the throne. While Grimsby does have some singing to do, strong acting trumps singing ability for this role.
Gender: Male | Vocal range: E4–C5

Chef Louis
Chef Louis is the over-the-top head chef in the palace. He is always wild and frenetic. This is an excellent featured role for a comedic performer.
Gender: Male | Vocal range: A3–C5

Chefs
The Chefs are Chef Louis's assistants. The music in “Les Poissons” can be challenging, so good choral singers are a plus for this group. Your Chefs can also double as members of the Sea Chorus.
Gender: Any

Carlotta
Carlotta is the headmistress in Prince Eric's palace and Ariel's greatest human ally. This non-singing role needs to be warm and maternal to make Ariel feel welcome.
Gender: Female

Princesses
The six Princesses try everything they can to win the heart of Prince Eric. Since none of them possesses the voice Prince Eric is searching for, cast actresses who can create an exaggerated and comedic personality through song. The six Princesses can double as the six Mersisters.
Gender: Female | Vocal range: E4–G5

Pilot
The Pilot is the head sailor on Prince Eric's ship. This nautical expert who entertains the sailors with wild tales of the sea presents an opportunity to highlight a developing performer. The Pilot has a few speaking lines, but his singing voice is most important.
Gender: Male | Vocal range: Bb3–C5

Sailors
The Sailors are the crew of Prince Eric's ship. They are eager for adventure and ready to tackle a storm. The Sailors can be played by boys or girls and can double as Sea Chorus.
Gender: Any

Seahorse
The Seahorse is the court herald for King Triton. This non-singing part is a good role for a young performer with a clear speaking voice.
Gender: Any

Sea Chorus
The Sea Chorus is responsible for creating each world within the show. Look for performers who can move gracefully and are capable of being part of a scene without drawing focus. This can also be an opportunity to showcase some of your more skilled dancers. The Sea Chorus can double as Merfolk, Sea Creatures and Lagoon Animals.
Gender: Any

Sea Creatures
The Sea Creatures are the ensemble underwater animals in King Triton's court. They can include as few or as many performers as your production permits. There are several moments to showcase both dancers and singers in “Under the Sea.”
Gender: Any

Merfolk
The Merfolk of King Triton's Court can double as Sea Creatures.
Gender: Any

Lagoon Animals
The Lagoon Animals try to convince Prince Eric to kiss Ariel. This ensemble can double as the Sea Creatures.
Gender: Any
