First of all I familiarized myself with the location of the sequence- Central Park Zoo. I went through the first 'Madagascar' on dvd, freeze-framing the key locations and making layout studies & geographical notes.
Then reading through the script I start to jot down any thoughts, ideas for business and key images that strike me.
Then I thumb-nailed out the entire sequence-fleshing out the character business and camera angles
Lastly I worked it up on the 4x3 story board pads provided-I didn't get all the way through but had the end of the sequence covered in the thumbnails above.
The sequence as it exists here is not in the finished film although there is a climactic scene involving the animals being tranquilized. (All characters are property of Dreamworks Animation.)
