Some kids today might not know it but before the live-action films with CGI chipmunks that sing popular pop songs, there was a classic kids cartoon series where the famous trio of chipmunks sang their own original songs. Alvin and the Chipmunks have had many adventures over the years. As a fan of Universal Monster movies, I had to eventually come across this animated feature film, along with its counterpart 'Alvin and the Chipmunks Meet Frankenstein'.
