Relic Castle

So I wanted to know how do you properly format Emotion Bubbles. (Exclaim, Question, etc)
How can they be properly formatted? How do I add them to the game?

I have one more question.
How can I change the player's trainer card (the trainer sprite), usually you can change the Trainer000's graphics and that'll do the trick, but I don't wanna change the original sprite, usually the trainer informations on what sprites to use is in PBS metadata but it's not there.
