This is the Scratch code for the Jingle Tangerines that we used at Manchester CoderDojo on Sun 08 Dec 2013. It's designed to be connected to a MaKey MaKey board, with crocodile clips going from each of the MaKey MaKey key emulator slots for up/down/left/right arrows and spacebar ... to tangerines.
If you want to use it without the MaKey MaKey board, then I suggest you change the "When <key x> is pressed events to ones more appropriate for a computer keyboard (e.g. QWERT keys).
The variables have all been left on the stage as the project was designed to be a bit of fun and also some Scratch programming education with variables and lists.

Any errors or bad design are entirely my fault. I wrote it at 6am on Sunday morning :-)
