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.
The only way to have access to your Moshling Zoo is by being a paid Moshi Member 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.
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.
