You probably saw the name of this thread and thought I was messing around, but I kid you not, there exists a prototype made by Rare (and apparently playable start to finish) by the name of Mr. Bloopy. Mr. Bloopy is not your average blob sent from outer space riding in a bottle towards earth to save the earth from the environmental disasters of pollution. It is an educational, puzzle/platform game geared towards children to teach them about the dangers to the earth's environment. The game is pretty unique for what it offers especially for it's puzzle solving elements.

If you'd like to hear more about this prototype here is a link to a page.
