5230 T-Rex and Saichania in the VolcanoChildren will enjoy this set! It is huge and offers a lot of fun for them although collectors not specialized in this theme may pass. The new T-Rex has vivid red stripes and the Saichania is a very well made newcomer, with a ball joint in the neck that allows wide mobility to the head. The box is very large (55x37x20 cm or 22x15x8 in)
Saichania is a kind of Ankylosaurus, armoured dinosaurs with an intimidating clubbed tail, very successful during cretaceous period. T-Rex is a very well known dinosaur also from late cretaceous.
The set gives us a cave, waterfall, exotic plants, fossils (trilobite, ammonite and dragonfly in amber). In addition, two klickies well equipped to perform their jobs as archaeologists.
Kids can push a button to trigger the volcanic eruption.
They also can pull a small lever to generate a landslide.
If they are expert archaeologists, they will find interesting fossils
(the dragonfly in amber is lovely)
Finally, two comparisons.
a) Volcano in set 4170 is smaller.
b) A gang of three (T-Rex in sets 5230, 4171/5019, 5014)
