You Can't Make This Up.

Yoshi and Sakura the Chahuahua

So, we know Yoshi is a dog.  This was confirmed by the veterinarian and everything.   His best buddy is a cat.  This is also confirmed by the veterinarian.  Somehow, they got the whole species thing confused.  They spend their day chasing each other.  Normal enough for a cat-dog living arrangement, but they like to trade off.  Dog chases cat, then cat chases dog.  Cat jumps on dog's back and chews on neck.  Dog flips cat on back and proceeds to eat the cat's head.  This will go on all day. No blood is shed, but they are covered in dog/cat slobber.

Not only do they have their own identities confused, they don't seem to care.  They are just friends having a good time.

It should always be like that.
