Minor bug report: Monster's animation data is incorrect

[BenjuKatchowee]

His down note animation shifts his feet upwards almost as if he's jumping or beginning to float, and his up note moves his feet downwards.

This will most likely get resolved when Week 7's source code goes public but I just want to know if it will affect the PNG file of his sprites since I would like to make a skin mod based on it. Surely not, right?
