- Celebrate the holidays in style - mouse-style, that is! Join Geronimo for his first-ever special edition. It was Christmastime on Mouse Island, and I couldn"t wait to celebrate with my friends and family. But then I discovered that they were all traveling out of town for the holidays, and I"d be spending Christmas alone! I was starting to feel like a real grinch. Would this be my loneliest Christmas ever?
