'When I Grow Up I Want To Be A Dinosaur' is a short comedy film, about Jeffrey, a 10 year old boy sick of people thinking he's a diarrhea face for wanting to be a dinosaur when he grows up. He doesn't want to be a sailor, a mechanic, and especially not an international pop sensation. He is sick of the school bully, the principal, and his mom.
After hearing his mom plans on sending him to a psychiatrist, Jeffrey sets out on an adventure to live life on his own. His best friend Lavender tags along. They stumble across a clubhouse in the middle of the woods. His mother realizes the kids she was babysitting are gone, so she sets out searching for Jeffrey and Lavender. Meanwhile, as the sun sets, Jeffrey decides to light some candles inside of the clubhouse.
The clubhouse goes up in flames. Jeffrey saves Lavender from the fire. When all is said and done, and the clubhouse is burnt to a crisp, Jeffrey's mother finds him and finally says she is proud of him. Jeffrey then re-evaluates his life, and decides from now on, he wants to be a firefighter. Not a dinosaur.
