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.
