Help in identifying PENGUIN Movie!?

No, it's not Happy Feet. No, it's not March of the Penguins or the Madagascar penguins either. It's an obscure title I remember watching on VHS when I was little. It was a 2-D cartoon, and it tells the life story of a penguin, from chick to adult. He(it's a male) was blue in colour, name was Casper or somethin like that. I was traumatised when he as a chick fell into the icy water (he was staring at his reflection) and nearly drowned, but somebody saved him. He has this female penguin pal (eventual love interest), I think she was pink. They grow up. The duo got stranded in the ocean when the ice shelf they were on broke off and drifted away. They met a black macaroni penguin, who acts as a cool sidekick. Then, they end up on a fishing trawler, where the macaroni tries to elude the fishermen while blue saves pink. Eventually, blue & pink meet up with their herd and the macaroni leaves them. And the circle of life continues. Oh, and there was a theme song! Can anybody help identify this?
