My kids are just now getting interested in dinosaurs. I don't know about tacos because we haven't given them any. I cannot imagine the mess I would have to deal with!
But...this could work. Imagine going to the zoo for Zoorassic Park and immersing your kids in all things dinosaur, then bringing them home for a taco dinner with dinosaurs as well! They will not get enough of it!
They also come in the TriceraTaco holder.
