It was Valentine's Day in New Mouse City, and I couldn't wait to celebrate.

I had sent valentine cards to all my friends and family members.

But when I opened my postbox on the morning of February 14th, it was empty.

Had everyone forgotten about me? Was I destined to spend Valentine's Day alone in my mousehole, sobbing, with only my pet fish to console me?

It was starting to look like a true Valentine's Day disaster.
