This depends on what you think is the most rare moshling.
HOBBIDIDANCE is the code to enter to get the Radiant Rosy Rose which you then plant with two other seeds to get Roxy the Precious Prism.
There are other moshlings which are probably more rare because you have to purchase a specific item to get the Limited Edition Code for the seed to plant to catch the moshling. Not everyone is going to be able to purchase those items, making them the most rare.
because he is a rare moshling and you need the code!
Yes Nipper is an ultra-rare moshling. You can only get him by buying the moshling zoo ds game. It comes with a code for Nipper.

Contributors have said that I.G.G.Y is the rarest moshling. Because of his rare seed combination, I.G.G.Y is the hardest moshling to get. Another difficult moshling to get is Roxy becuase a moshi monsters moshling collector's guide needs to be purchased to find out her combination.
