Noisy Star (sometimes known as just "Noisy") is a blue female explorer star from Star Catcher, Stuck Truck, Louder!, Dora Saves the Game and Star Mountain.
Her ability is tooting out loud "honks" like a horn. She does this to chase away bad and scary animals or does it just for fun.
Noisy Star also has the ability to warn Dora and Boots about Swiper.
- In Stuck Truck and Louder!, Noisy was referred as a male, but she is actually a female. It is possible that there are two Noisy Stars looking alike, or that they just mistakenly called her a male.
- She first appeared in the episode Stuck Truck.
