HELP! Monsters vs. Aliens

My son, Zac, is OBSESSED with the movie Monsters vs. Aliens. He is not giving up with asking 100 times a day for the set of toys from McDonalds, despite me telling him that they don't have them anymore. I wondered if any of your children have them and are done playing with them and willing to give them to Zac. He is specifically looking for Susan, Bob, Dr. Cockroach...he has Link, Insecto and the Robot Monster. Any help would be MUCH apreciated. Thanks! -Kris
