<p>If you really buyed "
it" as a Guest, it appears on your IP Guest account /<i>on your Guest account on your iPad, that is linked to your iPad so you cant connect to it on PC, another iPad or Android</i> So yes, you are pretty much screwed. But I think if you contact support that could transfer your skin. But its same as in any other game or app. I mean - you buy 20 000 gems to Castle Clash...Can you transfer it? Its just game money and money stays on your account. If you could transfer skins, you just could start a new acc, farm a bit, buy a cheap skin and than just transfer to other acc...
Anyways, you
should contact Miniclip support or
Agar.io support, and you may get an answer to 48 hours.
Have a good day.
