I have found the answer to the question that is lost, and I'm afraid its sad tale of plagiarism, sort of.

It's been bothering me for a while, I was convinced that I could remember a previous series that involved a polar bear and a moving island. It wasn't until a most random conflagration of conversational points that I stumbled upon the answer at work.

Noah's Island.



Here's the plot courtesy of wikipedia:

"The series focused on the adventures of a polar bear named Noah (voiced by Ron Moody) and a bunch of other animals who had been captured and were en-route to a new life in London Zoo. However the ship they were on was wrecked in a storm and the animals escaped. They find themselves on a mysterious floating island, a piece of land which has broken away from the Canadian coastline. The island becomes a sanctuary for a number of homeless animals. They work out how to get the island to co-operate with them and set off on a quest to find an uncharted island called Diamentina, while picking up other animals in peril along the way. Once they arrive there, it turns out to be more sinister than they imagined."






Ok not exactly the same but lets just highlight some key points here:

1. Storm leading to wreckage on an Island.
2. Polar Bear.
3. Moving/floating island.
4. And this is the freaking doosey...they get the island to co-operate with them...that's freaking right co-operate with them (can't remember how maybe they go to a shack and talk to freaking ghosts!!!).
5. It turns out to be more sinister than they imagined.

Come on now Mr Abrhams admit it, so maybe you caught and episode once and just didn't remember it.

Now that I think on it Lost could almost be a sequel. So the animals have been living the good life safe on their island, along comes Jack and the team BOOM bye bye mister polar bear saviour of the animals. Your a sick puppy Abrhams, a stone cold mother.

Also did I mention it was British, thinking outside of the box since the dark ages baby.

Sweet.
