The Chipmunk Adventure (1987)
This was a pure nostalgia trip for me. As a kid, I was a HUGE Alvin & The Chipmunks fan. I had nearly every toy available, and I watched the show whenever it was on TV. Naturally, when a movie came out, I made my dad take me. I remember it so clearly. We were in Florida visiting my grandparents, and I somehow convinced him to take me.
