Angry birds PRINCIPIA:Level 1-1

The bad piggies stole the birds eggs again and run now at PRINCIPIA WORLD! We must defeat them, but our slingshot broke, we must use a different weapon.
A engineer bird built something he called a cannon!The cannon is very powerful, use it to defeat the bad piggies and take back birds eggs! GOOD LUCK
