Requires getting back on Mama Turtle while she is at the right. The safest way is to have a normalized fall speed with either a full height jump or falling from the ledge above. If suitless, walking off the right ledge when she hits the left wall can be a good indicator to help land on her safely. Shrinking Samus' hitbox after touching the turtles back will also usually help. While near the right wall, shoot the item and grab it. If the shot misses, carefully fall back down and safely land on Mama Turtle again. After grabbing the item, fall on her again to avoid taking a hit; jump to the left at the top of the ride to escape the water safely.
