There's no information on the Secret 3 Moshling yet.
you need to type in H6FJNA9D8Y9W and you'll get a Hip Hop Hibiscus. Make sure you've planted it with 2 other plants. Wait for about 6 hours (probably overnight) and you'll have Blingo (although some call him secret 3)!
If you mean Moshi Monsters then i know number 2. number 1 u can find elsewhere. so to get number 2 get a membership and be a super moshi when u finish it the egg will hatch. The moshling will be Lady GooGoo. :)
You type in the Arby's code box moshling zoo1. You will get a million rox, and then you go to main street to buy the flower for a million rox. You plant it along with two other plants, and then you will get Elly the elephant.
I know all the secrets firstly there is Roxy for that u type in :hobbididance: in the mopod code then go to ur garden and you should see a radiant Roxy rose plant that with 2 other plants and wen their grown u should see Roxy there is also a squid called squishy if u go to the underground disco u go to the right of screen next to the man u should see a pack of moshlings and u should see a squid but i don't know how to get it there is also a little purple and pink thing on a rock wen u go their that's bonkers i do know how to get bonkers its purple daisy , black moon and red moon
