Searching for an old shmup from my childhood

[Null]

Hi,
like the title says, i remember me playing a shmup in the days of win3.11/dos. And i dont know the name of it.
All i can remember was that your ship was of beer bottles and you would shoot with crown caps. I think the main character was a squirrel. But do not quote me on that.
Has anybody any idea which game i am talking about? I know its not much i am offering but maybe someone here can help me out.

Thanks
