Since its debut in 1996, DEXTER'S LAB has been one of Cartoon Network's top-rated shows. Now Scholastic teams up with the boy genius and his pesky sister Dee Dee for original chapter and picture books
It's Dee Dee's birthday, and what she wants more than anything else is a pony. So Dexter decides to build her one in his lab. Dee Dee is delighted with the pony -- but then she wants it to fly. And talk. And play the radio. Before he knows it, Dexter has created a monster! Can he conquer his own invention... before it gallops crazily off into the sunset with his pesky older sister?
