If only it was TDW. Their upgrade kit is arguably as good if not better than PE and it is cheaper. I believe you need two different sets from PE to complete Volcanicus.
Well it turns out letting my 2.5 year old play with G1 Trypticon was a bad idea. He snapped off the two chest pegs used to attach Brunt in City mode and Full-tilt in Dino mode.
Anybody got a junker Trypticon I can harvest the part from?
