About Unicorns
First Steps
You will want a starter kit, and a free Redelivery Crystal
When you open your starter kit, you will have two starter cradles and a unicorn radish.
Rez your cradles, then click them once to intialize them, then click again to birth. Once birthed they will be frozen, and their home position will be set to where they are at the moment of birth. You can move them and reset their home position from their menu, you can adjust their range, and once you are happy with that, you can unfreeze them.
Once unfrozen, they will move around (occasionally making noise if you enabled sound).
Your unicorns will breed if they are frozen, so if you are concerned about simulator performance you can leave them frozen, however frozen unicorns will not make sound.
Unicorns do need to eat, they like unicorn radishes, so make sure you rez your radish near them. Unicorn Radishes will feed one unicorn for 2 weeks, so it will feed both your unicorns for 1 week.
More unicorn radishes can be bought from Xundra's Stuff or you could purchase a farm and grow your own unicorn radishes from seeds.
For Science?!
You can also send your unicorns to the great beyond, for science! Such a worthy sacrifice will reward you with 10 star points.
Redelivery and Updating
The redelivery crystal is used to redeliver your unicorns in the event they become broken. The should not under normal circumstance become broken, but incase they do, they can be redelivered. They can also be redelivered in case of a needed upgrade.
Updating a unicorns is easy, you just need an updated redelivery crystal, then click each of your unicorns and chose "redeliver" from the menu. Once they've vanished, click the redelivery crystal and choose "Get All", and all the unicorns will return at random spots around the redelivery crystal.
Redelivered unicorns maintain their home position, range etc, however they return frozen with sounds off. So you will need to renable those things if you want them.
