Not to interrupt the fun with a My Little Pony lesson, but in case y'all were wondering the boy ponies were called "Big Brother Ponies". The fireman one's name is Chief. No construction worker or biker ponies, but there WAS another boy pony who was supposed to be kind of Native American-like. His name was Wigwam, and he had tee pees on his butt.
EDIT: Haha, I just looked it up and discovered that there WAS in fact a construction worker pony. His name was 4-Speed and he came with a hard hat and had a dump truck on his butt. There was a cowboy named Tex who wore a cowboy hat (cactus on his butt), and a sailor named Salty with a white sailor hat and a ship symbol. So wow, that's 4 out of 6! Two more and you really WOULD have "The Village Ponies"!
