How to Get Roxy
Go to the login screen for Moshi Monsters and enter "HOBBIDIDANCE" without the quotes in the box for secret codes beneath your password. Log in to your account.
Go to the "Moshling Seeds" store on Main Street and purchase any two seeds. Select "To My Garden" on the left side of the screen. Check your Seed Cart and you'll see the two seeds that you purchased and a new seed called Radiant Roxy Rose. You'll see three dirt plots where you can plant seeds.
Drag the three seeds to the dirt plots to plant them. They can go in any order. Wait roughly five to six hours for the plants to finish growing, and then return to your garden. You'll see Roxy wandering around it. Click on Roxy, and then select "Keep It" to adopt this moshling.
How to Get Blingo
Purchase a copy of "Buster's Lost Moshlings: A Search-and-Find Book." You can get a copy through the store at the "Moshi Monsters" website or through most online booksellers. Flip to the back of the book, where you'll see a large red blurb telling you about the secret code for Blingo. The actual code is in a white bubble next to the red blurb.
Hold the book up to a mirror to get the code for Blingo. The code is reversed, so you'll need a mirror to see it properly. Go to the login screen for "Moshi Monsters" and enter the code in the secret codes box underneath the password box. Log in to the game.
Go to the Moshling Seeds store and purchase any two seeds. Select "To My Garden" to access your garden, and then click on your Seed Cart to see the two seeds that you purchased and the Hip Hop Hibiscus seed.
Drag all three seeds to the three dirt plots in any order. Wait roughly five to six hours for the seeds to mature, and then return to your garden. You'll see Blingo wandering around it. Click on Blingo and select "Keep It" to adopt him.
