Grounded - Climb the Wheelbarrow easily without building
All very easy jumps. The place where I crouch, make sure you stand up again, so you can sprint and run onto the leaf below.
Natural Explorer is not required, just Aphid Slippers, though Natural Explorer makes it much much easier. You don't even need a Dandy Tuft for the long jump with Natural Explorer 2 or 3. (Natural Explorer Mutation is unlocked by discovering 20/50/80 Landmarks.)
