T-Rex is a traditional cache which is part of the Dragonball series. You can treat this cache as an indiviual cache or as part of the series. If you plan to do more of this series (highly recommended) then I suggest look at all the others first and plan ahead and take notes or photos of everything on the inside of the lid of every cache.
