Your pets are getting hungry, click on the food for the pet that is on that page to feed it. Reset the hunger by clicking the green flag. And when you want to stop the hunger from getting larger, click the red stop sign. The arrows move from one pet page to another, just click on them and you can see our other pets!
This idea is from a video that I watched and added on too. The creator of this code video is Zoey from the Scratch team. Please check them out, maybe you will learn something that you don't already!
