Its an older movie, maybe early 80's or 90's used to watch is all the time as kid... its about a family, I can't really remember much but they had a cockatoo that was really smart and followed them everywhere. There were about 3 or 4 kids and a mum and dad, I think. They went on a cruise... on the cruise there was a man who was looking for the same treasure as them, he was really fat and had an accent... I think it might be an english movie anyway he would chase them around the boat because they had the map... they eventually found the tressure, it was underground and had a pile of gold coins inside..
Does anyone know what its called??
