Try and make the cow stay in the air as long as you can. You can press the up button to make him jump. You also have to dodge the ball and don't hit the pool or you will drown. Press space to restart.
How I came up with cow in a pool ... I was ill one day and wanted to make a game. I told my dad I needed my Calpol and he thought I said cow in a pool, so that's my game! Thank you Calpol and thank you dad! I played my dad's trombone on this game and I am only 9 years old.
