When Marli Bortoletto voices Mônica, she steps through a doorway into an alternate world where music becomes a bridge to four intertwined tales.
First, A Gruta do Diabo follows Angélica Santos as Cebolinha (Jimmy Five) and his friend Smudge as they explore a cave and confront the punishments of hell, a playful yet sobering adventure that blends humor with a moral about curiosity and consequences.
After that tale, the Fairy, Tetê Espíndola, appears in jaguar form and ushers in O Jacaré de Estimação. In this segment, a young alligator escapes from a zoo truck and winds up in Jimmy Five’s room, where he is cared for as though he were a small lizard.
Next, the Fairy reappears in the form of a macaw, signaling O Tocador de Sinos. In this part, Jimmy Five and Smudge encounter a giant church sexton and discover his hidden musical talent, a discovery that brings a blend of humor and warmth to the story.
Finally, in A Sereia do Rio, Tetê returns as a mermaid and sings the theme song. Monica captures a mermaid from the sea, but Jimmy Five tries to exploit her for commercial purposes, which hurts the mermaid’s feelings. Monica steps in to defend the mermaid from exploitation.
