Well a category playing with all the dinosaurs, have fun

Oohh, definitely will want to look into that, get a run up as soon as possible. Very exciting! Probably going to use raptor first since it's going to be a run killer and you might as well start over if your raptor-run is bad.

I assume it means we have to fight and win 8 battles with all dinos? Or is this just unlock all dinos?

Unlock all and play too
