I think it would be really cool if we had a sakura-themed pet color. In terms of pink stuff, I know we already have Dawn and Sweetheart, but Sakura could focus on paler pinks with some white, and be generally less cutesy. They could have sakura petals on them like how the Glade pets are all leafy and stuff, and they could have elegant poses like Glade or Glacier do. And if you want a region to associate the Sakura pet color with, there's always Shengui Guo. Heck, maybe the Sakura Potion could be a special pitcher found in Shengui Guo that you then fill at Peka Glade, so it's another variant of Glade like Harvest is. EDIT: Ooh, the vessel you fill could be a fancy ceremonial teapot!
