Have you ever seen a creature like this before?

This strange "thing"crossed my path while on the roadway. Being the curious person that I am, I turned around to check it out. It was about 12 inches long, yellow, orange, beige and black. AND its toes were humongous and long!
At first I thought that it may be someones pet that got out but this "thing" was too mean looking to be someones pet. It was the mean look that got me! You know the kind of look your mama gave you when you were naughty......That kind of look. When it turned a couple of times and gave me "that look" I can sincerely say that I was scared. Then it puffed up at me.... 
I used the zoom feature on my lens to take this picture since I didn't want to go close to it for fear that it may attack me. Yes, I am a curious coward and proud to admit it.
I forgot to mention that I was driving on Reems road in Surprise. I stopped fairly close to the fire station on the corner of Reems and Mountain View.
I am from Hawaii and we have the Chameleon Lizards there. This creature was way different! It reminded me of the creatures on the Simsons - the ones that had mutated due to the nuclear waste that Homer was throwing into the lake.
Does anyone out there have any idea what this may be?
I believe it is called a "Horned Toad". If you google it, you will see several types of them...and this sure looks like one!
