Animal, vegetable, mineral - name all four

Answers tomorrow. Was minding my own business at a red traffic light (unfortunately with my foot on the brake) when a huge dumper truck rammed me up the backside. Poor car is very bruised but capable of travelling to the blipmeet at the Newport Wetlands this weekend (or maybe I'll be given a rental one as it looks like it will be a write off - what a bummer in both senses...)
