You have to KO them to move on with your journey, sorry :(

Happygiest: If you defend he heals you, if you attack him he just does a light jab. He is feeling good. He has the most health out of the five

Madgiest: When you defend he talks to you about his anger, of you attack him he gets angrier thus; making him have more attack power. He has the most attack power out of the five

Woozygiest: If you defend, 30% chance hit herself, 69.9 percent chance she just talks giberish, 0.1% chance she accidently KOs you. If you attack she just gets more dizzy thus; making her faster. She has the most speed out of the five

Sadgiest: When you defend, he just beats himself up with words and cries, his tears burn your skin, when you attack he flails at you; not even noticing that you have been hurt. He has the most defense out of the five.

Mellowgiest: She is very simple, if you defend she attacks, if you attack she attacks. She doesn't hate you, She's just doing what she's told to do. She likes to listen to music while not fighting anybody. The most normal one out of the five. She becomes a friend later on.....

If you were wondering if the Ghost merchant was apart of the Emoti-Ghosts, he is not. He is just a normal ghost.
