How do you get a moshling with no seeds

You can get moshlings without buying any seeds if you complete some missions like the super moshi mission. You can get Lady Googoo by doing that. But u have to be a member to complete missions. Sorry. But if u r not a member, u can still get two moshlings in your room. But that's it. Just buy some seeds at the seed store, plant them, wait for them to go and enjoy your moshling!! Hope this helped:)
