Not bad ........ not bad at all.... But I also counted four as well.
I got one similar though. I might post it during the week some time. Until then try this riddle..... We are very little creatures; all of us have diffrent features. One of us in glass is set; one of us you'll find in jet. Another you may see in tin, and a fourth is boxed within. If the fifth you should pursue, it can never fly away from you. What are we?
