Developer: grumpy Happiness is Beethoven's Ode to Joy. So to welcome the new year, PLEO does a lovely dance.
Unzip the file(s); Copy the file(s) to the root directory of an SD card; Turn off your Pleo; Put the SD card in your pleo's slot; Turn on your pleo. Your pleo will then run the skit.
Turn your pleo off; Remove the card; Turn your pleo back on; Pleo will be back to normal!
