The Impossible Blooks in the Game to get is the Donut Blobfish, Blizzard Clownfish, Rainbow Jellyfish, Lemon Crab, Pirate Pufferfish, Crimson Octopus, Rainbow Narwhal, Blue Astronaut, Purple Astronaut, Sandwich, Tropical Globe, Frost Wreath, Poison Dart Frog, Light Blue, Black, Red, Purple, Pink, Orange, Lime, Green, Teal, Tan, Maroon, Gray, Mint, Salmon, Burgandy, Baby Blue, Dust, Brown, Dull Blue, Yellow, and Blue. They are the Hardest blooks to get in the game because you cannot get these blooks through Events or Unboxing, The only way as of April 2023 to get these, is by Hacking. Although this is my opinion, many people may or won't agree with me.
