I am making a short film about a dinosaur leaking onto the internet. He needs to have a job or hobby.
For example: my goblin goes clubbing because he hits people with clubs
My dragon is a chef because she burns people and eats them. Etc
His job can be a careworker. If the children misbehave he just simply thumps them one with that big tail of his or swallows them and when ten minutes is up, he gaggs them back up. His hobby can be that he goes down to the local dinosaur park and every saturday he takes part in 'who can eat the most humans in three minutes', of course he wins everytime.
er how about your dinosaur is a building site worker who smashes buildings with his huge body and treads on them with his massive feet? so that people can build new ones in their place.
a life insurance salesman because his cousins got wiped out when the asteroid hit!: D lol
