A Pterodactyl and Dragon Castle????

Most 3 year olds ask for cars, balls maybe some new crayons? Any of these things would be fine but not my kid. All Christian asked for from Santa this year was for a Pterodactyl (I just had to use dictionary.com for that one) and a dragon's castle. YEAH RIGHT!! Where does one find such objects I ask?? Not at Target, Walmart, Big Lots or Kaybee toys (just to let you know). Don't think I haven't tried to outwit him either, I tried to give him other ideas for toys to ask Santa for but he marched right up there, sat on his lap and told him what he wanted. Not to mention we've been "done" with his Christmas shopping for a month. How much does a 3 year old need?? ARRRGGG!! I can't find a pterodactyl, I can hardly even spell it, and I don't know what a dragon castle is but I guess I'll keep looking. After all, he did ask Santa for it.
