BOBA is an image macro series that features a picture of the head of a smiling puppy on a color wheel background split into six separate colors. Usual derivatives are often accompanied by two lines of text written in a guidance or advising format with the advice given usually being very poor, unethical or deplorable.

Since its debut, the series has spawned dozens of spin-offs referred to as Advice Animals. In these variations, memers replace the dog's head with a different animal's or a human's head, adding advice that is reflective of the character's archetype personality and using the same two-line image macro formula.
