Create 2-minute animated birthday video with Dr. Seuss theme

We have created a ~2-minute song to wish our classmates a happy birthday. We would this song to be the background music for a video that features several characters from various Dr. Seuss children books The video would start with Horton the Elephant and "the Whos" announcing to all the Dr. Seuss characters that "It's your birthday, and it's time to celebrate." The video continues with everyone (including/featuring Thing 1 and Thing 2) coming together for a party and birthday cake. Please listen to the attached music file and refer to attached document for song lyrics and images of the characters
