(ignore the pony, i didnt want to screenshot a random person and i have 214/150 ponies :/ )

Ive been seeing this a bunch around the safe server, and i just dont see the vision. at first i thought it was supposed to be an extension of the dress, but ive seen ponies that dont have the dress accessory on use this and now im confused.?? its always this specific tail shape and then the first two colours are coloured the same as the grass to blend in, so the tail looks like its floating.
