Cardi B is headed into deep waters…

Nickelodeon has announced that the 29-year-old half-Dominican American singer will appear in a special episode of the hit preschool series Baby Shark’s Big Show! airing on April 15 at noon ET/PT on Nickelodeon.

Grammy-winner Cardi will appear alongside her musician husband Offset.

“The Seaweed Sway” follows Baby Shark (voiced by Kimiko Glenn) and William (Luke Youngblood) as they meet the ferociously fun rap icon Sharki B, who is swimming into Carnivore Cove to perform her splash hit dance craze, The Seaweed Sway.

Sharki asks Baby Shark and William to show her around town before her big concert and perform The Seaweed Sway with her on stage that night. As hard as William tries, he keeps messing up the final move of the dance. Luckily, thanks to the help of his friends and his musical icon Sharki, William learns that the true secret to great dancing is doing it his own unique way.

It’ll be the first time Cardi B lends her voice to an animated character.

Her finned alter ego is described as seven seas-flashy, awe-inspiring, and ruthlessly fun—but always 100% herself and fin-spires other fishies to do the same.

Guest stars Offset plays Offshark, a cool fish with a great vibe and a huge Sharki fan; and the couple’s real-life baby shark Kulture will bring to life Kulture Shark, Offshark’s three-year-old daughter who is excited to attend Sharki’s big concert with her dad.

Season 2 of Baby Shark’s Big Show! is set to debut later this year.
