Welcome to FJ. You've already gotten great input from folks here on an "all croc" style. The shoe to get if you want the most total shoe coverage is the shield tip like Devin has shown. And with complimentary colors, it will win you prizes 9 out of 10 times.
As my friend Pulp has noted, many of us have large collections of FJ with a variety of styles. I use the Asymetrical, and have paired various colors with the croc, lizard, tortoise, snake, and patent accents. You'll trust me when I say every pair of shoes is always noticed and commented on. Homies and TNT go big as well. The message is, you don't need the whole shoe to be croc to get the oohs and ahhhs you aspire to.
Welcome again. Check out the MyJoys tool and have some fun!
