Turn it into a game. Can you get Scratch to sing happy birthday when all the candles are lit? (Hint 8: Make a new “all sprites” variable for each candle. For each candle, set the value to unlit to start with. Change the value to lit when it is clicked.) (Hint 9: In the cake sprite, when green flagged clicked, loop round forever, checking if candle 1 is lit AND candle 2 is lit, etc. and play music when all lit.) (Hint 10: Scratch sounds include a happy birthday tune.)
You need to complete Challenge 1 and 2 first.
