You can buy the base little legends from the store, not the recolors. So if you're like me and wanted the spicy chicken, have fun rolling away hundreds of rp because there are 24 different dudes in those eggs. God forbid you want a 3 star
You're kind of both right. You can buy eggs for any species (Any random Shisa for example), or directly purchase specific colors from a rotating selection (ex: Firecracker Shisa).
