Query: Another nightmare by mattel

Well Mattel has done it again. It's bad enough that the Barbie toys that had to be put together for my girls throughout the years were a nightmare, now this stupid toy for my nephews is just as horrible. Talk about a waste of time and money. Someone should sue Mattel for ruining many a Christmas. Maybe then they'll start taking some pride in what they manufacture. Or maybe their toys should come already assembled? Wonder how long it would take them? Don't bother with this T rex toy. Didn't want to give it any stars.
