Caterpillar idea.

After discussing our ideas in our groups i feel like i have made some successful progress in the development of my animation idea. I have refined certain aspects of the story and broken it down in to 6 main actions.

1. Introduction - introduce the main character and the two horrible caterpillars
2. Emotional attachment - Main character gets knocked of branch and left to look up at the other characters, for looking different.
3. Sympathy - mean caterpillars turn into butterflies, and the protagonist feels sorry for himself
4. Change of attitude - the protagonist accepts himself for being different and excels.
5. Panic - protagonist worries that it will not change into a butterfly
6. End - sudden change and protagonist turns into a bright beautiful butterfly. 

The stages above are the main stages in the story. I want the first two stages to consume the first 15 seconds of the animation as it sets up the story. I then want the third and fourth stage to take up 15 seconds each leave me with 15 seconds to finish the story. Ideally i would like more emphasis on the caterpillars change into a beautiful butterfly then the worry about changing. So maybe it could be split 5seconds to 10 seconds. Or even miss out the worry about turning into a butterfly? This still needs development.
