They have a simple design and no animation. Except for their surroundings, but it's limited.
The "Flashed" Eds appear only in animations that have the title "The ..... Ed, Edd n Eddy Flash", and a misleading description/word that only sometimes tries to be relevant to the animation. It often starts out promising (with fancy menus or actual animation), but gets cut off after a few seconds, followed by Ed, Edd and Eddy doing something completely random.
The first animation with these characters was called "The Best Ed, Edd n Eddy Flash".
