You can use any curriculum and tweak it to suit your needs.
The UPC has a Children's church program. I liked a couple of them, especially the "Good Ship" or whichever has a ship theme. That was probably the best out of them all. Master's Care was pretty good.
The Power Tool Box is an older program, but it is great! We had great success with this one.
This is also a very awesome Children's Church program!
