Here is a drawing of the game i made up, “Angry Birds Off Piggy Island”. This shows the birds determined and ready to battle the pigs!
The scan is not very clear but the birds in this picture are Bomb, Chuck, Matilda, Spin Bird, Hal, and Thunder Bomb Bird.
This older post, shows a look into the levels of “Off Piggy Island”.
Thanks for looking at my drawings! – Brendan
