It's a plastic Rex, the T-Rex, from Toy Story. It's about six inches tall.
You pull his head off and load him up with Smarties candies, then put the head back on.
As you turn the head from side to side, a candy comes out a slot in his back and rolls down the slot to the end of his tail, so it's a candy despenser. Way cool.
I liked the Lion King ones where you would push a button and they would say something. i had a simba one and someone stole it (yes people at my school are pathetic) so then i bought another happy meal and got timon. Those things were SO entertaining. I think my timon is collecting dust in my room somewhere
my favorite is the Marvin the Martian... he's standing on a basketball on a rolling platform with his arms out to the side, and when you roll him, he bounces up and down on the ball... not too interesting but i loves me some Marvin the Martian...
