Growing Blue

Growing Blue is the Cat fruit gathering daily event that occurs on Thursday. Player will face Alien enemy for most of the time in these stages. By clearing any of these stages, you might get either a Blue Seed (most likely) or a Blue Cat (likely) fruit or an Epic Cat fruit (unlikely/rarely). You also have a small chance to unlock and play the special stage Catfruit Jubilee.

Blue Illusion (Hard)
Not a tough stage. If player has done Into The Future chapter 1, this stage won't be a big problem. Cat recommended are Macho Legs Cat, Neo Cat and Castaway Cat. They are easy to obtain and really useful against aliens. Don't forget to bring a couple of meat shields and some long range attackers. They will cheese the stage.
