Eye movement?

[Allbait]

Giving mew animations to characters can be fun... But I hate having the character's eyes looking to the wrong place... Especially Marth since in his normal wait animation he looks to the side and if you give him a new wait animation that makes him face forward his eyes look to the side... I wanna know how to control the eye movement to change where they look... And also where is the place where this kind of thing is set: o.o; PSA? Texture animations? I have no idea .___.'
