Positioning the Puyo requires it to perform a big jump then start falling with a frame perfect freeze. One possible setup stands on the left tile of the right side and lets the puyo jump up taking a contact hit. Then so long as the puyo isn't on the very edge, it will do a big jump. Clip onto the puyo by doing an aim down jump and switching to a forward diagonal at the right time.

Requires:

Dev note: 1 hit per attempt, 7 for leniency, which is reduced if Samus can reset the room and farm the Puyos. FIXME: leniencies should be moved to helpers or some central location. FIXME: There is a normalized setup which can be described and most or all of the leniency can be removed.
