It might sound noobish, but I just want clarification D:

So.. Normal account: max 5 pet slots Gold Account: max 10 pet slots Gold + mystical plushies: max 20 slots?

Or do we need a GA + the plushies to get more than 5?

Yep, you got it right. :)

Oooh that's awesome, thanks! ^^

Hey, I have my own question ._.

If I activate two GA's in one month, do I get 10 extra pet slots per month :D that would be PWNAGE.

No, with the Gold Account alone your limit is ten, more slots can only be obtained by using a Mystical Plushie while having an active Gold Account.
