Call it Thalia’s big adventure…

The 40-year-old Mexican singer/actress will be lending her voice to an upcoming television special featuring characters from Dora the Explorer.

Thalia will provide the voice of the mermaid’s mother in Nickelodeon’s Dora’s Rescue in Mermaid Kingdom, set to air Friday night.

The story centers on the efforts of Dora and Boots to help Maribel—a lost mermaid they encounter on the beach—get back to her mother in the Mermaid Kingdom.

“Dora is such an iconic and important Latina heroine, and I’m proud to now be a part of the show’s ever-growing legacy,” says Thalia, a mother of two. ““I was thrilled to play a role on Dora the Explorer, a show that has touched the lives of many children around the world including my own child.”

Dora, now voiced by 7-year-old Fatima Ptacek, is a 7-year-old bilingual Latina who explores an “imaginative, tropical world filled with jungles, beaches and rainforests.”

In its more than 10 year history on the air, the Emmy-winning show has featured guests like John Leguizamo, Cheech Marin, Ricardo Montalban, Esai Morales and Chita Rivera.
