You can't get all the moshlings in one day because to get some of the moshlings you need to be a moshi member. Have fun playing ;-)
You can not get all the moshlings in one day because it usually takes 4 to 6 hours for your plants to grow to attract one moshling. Also you can only do one Super Moshi Mission at a time, so that will take at least ten days to get all of those moshlings.
You can not use one code to get all the moshlings on Moshi Monsters. There are several different ways to get moshlings, but you can only get one moshling at a time.
You can only get moshlings one at a time. You can get a set of moshlings by attracting one moshling, then attract the next one, until you have the set of all four moshlings.

Moshlings are attracted one by one as each one likes different seeds. You cannot attract them all at once.
You can not catch all the moshlings at one time. You can only plant three seeds at a time, then wait for the flowers to grow to catch one moshling. You can get moshlings by completing Super Moshi Missions, but you can only complete one mission at a time.
Free Basic Members can have two moshlings. Paid Moshi Members can have as many moshlings as they want. They may have up to six moshlings in their room/house plus they can have all the moshlings in their Moshling Zoo with one or more of each.
If you are a paid Moshi Member, you can have all of the available Moshlings, plus you can have more than one of each Moshling.

There isn't a secret code to get all the moshlings.
