A few days ago I picked up a fireman costume for Frank at the store. I gave it to him right away so he could play with it until Halloween. It came with a coat, helmet, a little ax and a fire extinguisher/squirt gun and he enjoys it a lot (as you can see here from his own unique pose in a photo taken by his seven year old sister).
The funniest part is that he calls his ax his "wax", I think because you can whack things with it. :)
