T-Rex Birthday Cake

What could be better for a 4-year-old's birthday than a scary looking T-Rex popping out of his birthday cake?  My poor 2 year old kept saying, "dinosaur scary,' in her cute little voice.  What a fun cake, though!  I really like doing different cakes.  Even the boy cakes are so fun for me!  

The head is cake with rice krispies molded around it to get the shape.  The claws (I know, they're really too big) are rice krispie treats as well, covered in modeling chocolate and 'painted' with coloring gels.  Cake is just chocolate frosting, green frosting, crushed Oreos and rock candy.
