Just press the griffin! But, the griffin will get hungry! So, to make it not hungry, just press the watermelon, and it will become less hungry. At the top left corner of the scratch project, there is something that says Hunger 0. Every 6 seconds it will change to a higher number. (By 1's.) Like I said before, just press the watermelon!
I made this by watching a video, but I did different things then the video. Check out the video: https://scratch.mit.edu/discuss/youtube/irhNLRWwhv0/
