You don't have to be a paid member to have a moshling, but if you are not a paid member you may only have 2 moshlings. Basic (free) members can not get moshlings that need Crasy Daisy or Snap Apple seeds.
It depends on the moshling. If the moshling is attracted to a Crazy Daisy or a Snap Apple, then you have to be a paid Moshi Member to get that moshling. If you get the moshling by completing a Super Moshi Mission, then you have to be a paid Moshi Member.
You can not take your Moshling for a walk unless you are a Moshi Member (paid).
You can not become a moshling on Moshi Monsters. You can attract moshlings to your Moshling Garden and collect them in your Moshling Zoo (if you are a paid Moshi Member).
Sorry, but you can not get Tiamo unless you are a paid Moshi member. Become a paid Moshi member and complete Mission 7: 20,000 Leagues Under the Fur to get Tiamo the moshling on Moshi Monsters.
You have to be a paid Moshi Member to have access to the Moshling Zoo through the Moshling Zoo Door on Moshi Monsters.
You have to be either a free Basic Member or a paid Moshi Member of Moshi Monsters to get the moshling Dipsy.
The only way to have access to your Moshling Zoo is by being a paid Moshi Member on Moshi Monsters.
Moshling Zoos are only available to paid Moshi Members. You should have a Moshling Zoo as soon as you start playing on Moshi Monsters as a paid member.
You have to be a paid Moshi Member to be able to get moshlings out of your Moshling Zoo.
No, you do not have to be a (paid) member on Moshi Monsters to get Peppy the Stunt penguin.
You can not delete moshlings on Moshi Monsters. If you are a free Basic Member, you can choose "Set It Free" when you get a new moshling, but the moshling that you set free goes to your Moshling Zoo in case you ever get a paid Moshi Monsters account. If you are a paid Moshi Member, moshlings go to your Moshling Zoo.
You can get Chop Chop on Moshi Monsters if you are a free Basic Member or a paid Moshi Member.
