; Archer Bute
; by Sonikku
; Description: Stands where you place it and shoots arrows. If Mario is above
; this sprite, it uses different frames and aims a bit higher. Like the flying
; Bute, if killed it falls to the ground and disappears in a cloud of smoke.
PROJECT = $03 ; custom sprite number of ButeArrow.cfg
