Sapphire is a precious horse. Every time he wakes up, he will ask you to join him on another player's pofile page.
If you follow his instructions, Sapphire will give you 10 when his age in months is an even number, or 1,000 if it's an odd number.
This horse cannot be sold.
You can increase his skills by using your Passes.
