To give him his muffin, press SPACE. To restart the muffin press "R". To give him his ball, press RIGHT. To make him play the guitar press LEFT. To make him lay down, press DOWN. He gets hungry and sleepy over time, so take good care of him! ENJOY!!!! :)
I want to say thanks to Scratch for giving me the idea to do this. Soon there will be a "Own pet puppy!!! 2" coming soon! P.S: you can personally name him yourself, but I named him "Max".
