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. At the top of the ride, jump to the top right ledge.
