Easter Ideas:
+ A Turkezilla, complete with beautiful pastel, Easter-y colors. (They only have a few colorations as it is, and seeing one with such colors would make them seem less evil and just so hilariously wonderful.)
+ A new Lopunny coloration of some sort.
+ A Shartile with an egg replacing the skull that they have.
+ A pet or two with different bee colorations, since they come out in spring, and actually have a lot of colorations.
