For example I have older design of mystic dragon, also their redesigns, also their NEW redesigns with a colored stripe. I have two Orange packages in English and in German, though the art is Identical (but one is the lighter print). But the languages are different :}

Old and new fairy drink, old and new monster alarm, lots of safary fruit variations (including in Turkish!!), jungle drink, ice tea, tropical, fruit crush, uncommon design of a LEMON taste, blackcurrant and apple (those in Italics are no longer on shop shelves! I saved them..!) If a package differs in design even by a little note like these two (one with German text and green oval on the left and this one in English and with a colored stripe) - they are both in my collection.

I love limited editions! I got some of the Animal edition, two from old Sports (?) edition, all but one from Pets edition, all from Filter edition (and I had to beg an online seller to send me the last one, without that I'd never finished the edition..!), all from newer Sports edition, all from Superpower edition, and all but one from the American Moon punch edition.

Right now there's a new Island limited edition (and I hunt for it - I have 7 out of 8, and still hunting) they were only made on 25th of June, there's still time.
