Oatchi in plush form
Oatchi is the best pupper the world has ever experienced. He will carry you and your pikmin you to victory on his back. He is a very soft puppy. If you hate Oatchi Louie will come to your house and eat you. Oatchi tries his best to serve you each and every day. His favorite food is cream of wheat, and he is notable for forming the second half of the musical duo Hall & Oates.
Over 12,000 Oatchies exist, and if you had a heart you would adopt one because they need cuddles to stay alive and the world is too cruel to have such a cute doggy... If you let him into your house, your life will be filled with unadulterated joy until the day death do you part. You will know you are loved each and every day by him. Oatchi is essential to a happy and fulfilling life, even if he doesn't have a wet nose to boop (he has a giant upper lip instead).
He will protect you and your pikmin, clean your dishes, lick dirt off you, and lay on your lap. He is the most useful dog the world has ever seen. Every Oatchi wants their owners to live a long and heartwarming existence; you don't get this from any other dog. He's such an sweetheart. He can also round up pikmin and pluck them from the ground.
If Oatchi dies he will be looking over you from heaven like a guardian angel, sending his best wishes to you and your pikmin. Most people don't know this and commit suicide when their Oatchi dies because of the dread that fills their hearts, but you must stay strong and care for another Oatchi because that's what Oatchi would have wanted. Oatchi wants the best for you because he loves you. Don't ever forget that.
