Emerald Reference Number: H2
Level: Meteor Herd
Character: Knuckles
Hint 1: Sunglasses.
Hint 2: The top of the steel beam.
Hint 3: Try getting to the suspended spring!
Difficulty: Medium

Where it is: Look forward near the beginning of the level you should see a
large structure you can climb. It's the same structure where you
fought Rouge/Knuckles in earlier battles. It's the structure
of beams in the very center of the stage. Glide over to it and
climb up to the top. Stand on the corner and look around on the
other 3 corners. Find the one with the spring and take it up.
Glide at your peak on to the highest platform you can glide to.
This platform should have a spring and 3 boxes and a long ledge.
Head over to the long ledge and inch over on it. It has a free
life on it so you know you are on the right ledge. Put on your
sunglasses and run to the spring at the end to be sprung up in to
the air. At the peak of your spring, glide to be at the perfect
height to get this emerald piece.

Emerald Reference Number: H3
Level: Meteor Herd
Character: Knuckles
Hint 1: Wear sunglasses on the moon.
Hint 2: The inverted blue tower.
Hint 3: Beyond the rings that you see using sunglasses on the moon.
Requirements: Sunglasses
Difficulty: Medium

Where it is: Alright, if you know how to get to the very top of the level do
it. If not, here is a path to get there. First, glide forward
to the structure with lots of bars. Its the same structure as
where you fought Rouge/Knuckles. Anyways, climb up to the top
and stand on one of the corners at the top. You should see 3
other corners and one should have a spring. Hit the one with
the spring to fly up to another platform. This platform should
have 3 boxes, a ledge, and a free life. It's the same one
as where you found the second emerald. Take the spring up and
glide over to the blue type structures. Fly over to the side of
the deep platform and climb up on top. There should be a rocket
that will take you up to the ARK ship! Just what you need!
Either cling on to the wall and climb around or land on the
platform and glide. Either way, glide around the bottom
platforms until you find the one with the flying type enemy.
Stand on here and put on your sunglasses to find another spring.
Walk over to it and glide at the peak to find this emerald
piece!
