The patch notes for 1.3.2.0 say that "Party Animals will welcome new characters and a series of outfits, replacing some of the old ones. So, if you have any outfits you're fond of, now's the time to grab them!"
If this means that old skins from the egg machine will be removed, I think it would be nice to have that pool move to the store pool, so we can buy the old skins with cookies. This would help people get skins they've wanted badly while getting rid of FOMO if they are never able to get the skin they want because of luck.
I am level 63 and the only skins I want are the little red riding hood skin for carrot and the swords skin for macchiato, but I haven't gotten either to drop for me in the egg machine. My last pull of 10 eggs actually gave me two epic skins, but they were both duplicates. I would be upset if I'm never able to get these skins because of randomness, so I think moving the old egg machine loot pool to the general store loot pool would be a good decision. If anybody wants to share how they'd feel about this please comment!
