This is a port of my old XNA/C# build of TurtleSim2000 to the monogame framework. (almost the same as XNA) I'm still working out the kinks to get it running just the same as it does in XNA.
Although all the source code is here, the art assets and other resources are not. I'll be hosting those somewhere else soon when I get the time to document the code better. for now you will only need Monogame. The game should compile just fine with that and the assets.
