So it was a while ago obviously, between 1993-2003, probably around the 1995 area
The movie surrounds around a bunch of sailors or pirates searching for some sort of legendary teapot of some sort (it was a children's movie so i didnt question it)
they sang a lot of old childrens songs like "what do you do with a drunken sailor", "my father went to sea sea sea" and such. Im sure there was a cave, or an island shaped as a teacup and there might of been multiple ones.
Mind you, when i saw this movie it was back when i lived in england, so it might not of been around in america
