I am looking to identify a cartoon from 2004 to 2006... The heroes live inside a whale and have the ability to transform into drop of water to go unnoticed. With them, there is also a mermaid who cooks... an episode where it was with Archimedes and has helped him defend his city against an attack...
Thank you for your help!
This is not The Marvelous Misadventures of Flapjack
The heroes (a captain, children, a mermaid) live in the belly of the whale (blue?). In the inside of the whale, it was like a ship with windows so you can see outside! An episode where the mermaid falls in love with a human on Earth and will be hard to leave and return to the whale... The heroes turn into drops of water is large enough, normally, this is the first thing that you remember this Cartoon ^^
Follow the fabulous tales of an impressionable young boy, Flapjack, and his two advice-giving best friends: the crusty old pirate called Captain K'nuckles and the wise-talking blue whale, Bubbie, whose mouth they call "home, sweet home." Armed with an overwhelming desire to be known as a true "Adventurer," Flapjack will do anything- and this means anything!- to follow his quest to reach a fabled floating island, no matter the number of insurmountable obstacles or overwhelming dangers that he might face in The Marvelous Misadventures of Flapjack.
Here's Bubbie.
There's a captain and a child, but no mermaid, however.
