Nibbles has numerous different diamonds to eat. They are each a different color and serve a different function. Only the pale purple diamond is guaranteed to be around long enough for you to eat it (in fact, you have to eat them to finish the level). The other diamonds are all bonuses, but they only stick around for a short time. We'll leave it up to you to discover just what the bonus each colour gives, but they all affect either the score, the length of the worm, or both. Be careful when going for these bonus diamonds, don't cut yourself off from the ordinary diamonds that you need to finish the level.
