How to make quiver be straight 90 degrees?

The quiver is usually sitting sideways on the archer, but I want to change it to be pointing straight up, how do I do this?

 

step 1: Convert your quiver sprite onto an angle that supports the upright position
step 2: Put 3 dots *red dots* in a triangular position, so that 2 dots are on the quiver in an upright position (One on bottom of quiver and one on the top of quiver), while another dot is in the centre of the archers hit box
step 3: line up the dots and draw an eye in the middle of the triangle
step 4: this is where it gets really difficult, you must now take a screenshot of this, send the screenshot to me, once you've done this I will send it to the pentagon so they can use there super computers to analyse it
step 5: Hopefully the pentagon will send it back with in 60 years (This is caused by a law stating that the american military can only release secret information 60 years after it was acquired)
step 6: insert it into your specially bought floppy disk drive with over 600TB of storage, and whalla you're done.
I hope this helped, with this information you should be able to make your quiver sit upright.
