How do you get a moshling with a code and a plant

You type in the code in the code box on the log in screen, and then you look in your chest or whatever it is in your moshling garden, and you have the seed you need for the coded moshling. Normally, you just plant the seed with 2 other random seeds, wait 4-8 hours, and then you will have the moshling! For example: Roxy, the moshling's code is: HOBDIDANCE. You enter that in the box, look in you garden, and in the chest you will have the Radiant Roxy Rose.
