Dinosaurs at my desk!
One series of collectibles I enjoyed gathering were of these multi-coloured dinosaurs from various soft drinks at "Lawsons". They came with a power card that can be used to compete with others in a Pokemon/Magic the Gathering kind of way.
But even better are these Dinosaurs that Pepsi promoted to coincide with the King Kong opening. Very detailed depictions of several scenes from the movie but I don't recall ever seeing that giant piranha-type fish. Maybe it'll be on the DVD.
