In Stage 1 of Old Odyssey, you can find the first Sun Stone once you reach the mountain
climbing section.
However, jump off the edge on the left and float down to find a bomb block.
Destroy it to uncover a 3D Warp Star and use it to travel into the background.
Work your way up until you see the cracked rock.
Break it to reveal the orange star door.
On the other side, jump into the cannon and blast through the rocks.
Use the next cannon to collect the Sun Stone on the right.
When you reach the area with the Waddle Dee trains, continue right until you find a bomb
block in the ground.
Destroy it and backtrack to the left to go under the mountain and find the rare keychain.
After you get the Hypernova ability, you will spot a Waddle Dee train with a chest attached
to the front.
Suck it up to collect the chest.
Inside is the next Sun Stone.
When you find the large vegetables, suck them out to break blocks that are hiding a locked
door and a key.
Use the key on the door to reveal an orange star door.
On the other side is another huge vegetable.
Use it to break the blocks and collect the Sun Stone.
In Stage 2, you'll find the first Sun Stone during the hanging boat section.
In between boats, you'll spot a bomb block holding up a key.
Break the block and grab the key.
Carefully avoid the hazards and jump out on to the floating platform at the end to unlock
the door and use the 3D Warp Star.
This will take you to the foreground.
At the top of the mountain is the Sun Stone.
The next can be found in the area with the crumbling blocks.
At one point you'll come across a fork with a large enemy on the right.
Destroy that enemy to reveal an orange star door behind it.
On the other side, cross the crumbling blocks while destroying the enemies.
Make sure to leave enough platforms to come back with the key in the background.
Use the key to unlock the door and collect the Sun Stone.
After you defeat Bonkers, take his hammer ability.
Travel to the background and fly up and to the right of the nearby door.
Drive in the peg to reveal the rare keychain.
In the section where you have to topple pillars, make sure to not destroy the one with a path
underneath.
Go around it to a 3D Warp Star and use it to enter the foreground.
Go to the left and open the chest to obtain the Sun Stone.
In Stage 3, during the laser pole section, use the pole to activate a switch in the background.
This will get rid of the metal blocks around the Sun Stone to the bottom right of the door.
When you reach the background area with the sloped floors, keep an eye open for a gap
to the top right.
Defeat the enemy on the other side to collect the next Sun Stone.
You'll spot an orange star door in a section with large cannons.
To reach it, fall to the right side and break open the cracked block.
Make sure to have the Fire ability since there's a fuse puzzle on the other side of the door.
Carefully carry the lit fuse to the cannon and collect the Sun Stone on the other end.
Once you use the 3D Warp Star to reach the area with the level exit, jump over the nearby
cannon and float to the bottom.
Hidden below is the rare keychain.
In Stage 4, you'll eventually come across a metal wall with a single bomb block.
Destroy the block to make a path forward as well as collect the Invincible Candy.
Quickly make your way forward until you see a bomb block on the other side of some spikes.
Break the block before time runs out and open the chest to find the Sun Stone.
Further on, you'll find a door leading to the next area.
Don't take it.
Instead, jump off and float underneath in order to get to a 3D Warp Star on the other
side.
Take that door to appear in the background of the next area.
Continue onward until you spot an orange star door.
On the other side, use the Archer ability to fire an arrow through the gap and hit the
target.
You'll find a Sun Stone in the chest nearby.
When you leave the orange star door, you'll find a Warp Star in a nearby barrel.
This will take you back into the foreground.
A little beyond there you will see a hole in the background.
Push up near it to find a secret area.
Jump in the cannon and position it on the right side in order to collect the rare keychain.
The Sun Stone can be found near the level exit.
Let the strong wind blow you past and use the Warp Star to return to the foreground
and collect the stone.
In Stage 5, you can find the rare keychain in the same area as the fuse and all of the
cannons.
The keychain is tucked away on the opposite side of the wall in a chest.
Return to the other side and light the fuse.
Make your way to the top cannon before the fuse reaches it.
This will launch you to a secret area where a Sun Stone is surrounded by ice blocks.
Use the Fire ability to burn the blocks away and obtain the stone.
As you progress, you'll spot an enemy in the background with a key.
Dash ahead to an area with a little dip and attack the enemy as he goes past.
Grab the key and use it on the nearby door to get the next Sun Stone.
After you get the Hypernova ability, work your way until you spot the male and female
snow heads.
Match them with their bodies in order to be rewarded with the next Sun Stone.
The final Sun Stone cannot be missed as it will appear after devouring the Waddle Dee's
wooden house.
Stage 7 will be unlocked once you collect all of the previous Sun Stones in Old Odyssey.
You can find the rare keychain once you enter a new area with an igloo sending out snowballs.
Avoid the snowballs and enter the igloo to find the keychain.
Eventually you'll come across a time bomb near the Waddle Dee trains.
Grab it and carry it to the other side of the tracks to blow up the blocks.
Enter the orange star door on the other side.
Here, you have to destroy both enemies before they escape with keys.
If you have the Ice ability, freeze one and force it into the other.
If you do fail, simply leave and come back to try again.
Once you do get both of them in one try, open the two locked doors and obtain the Sun Stone.
The last Sun Stone can be found in the chest before the 3D Warp Star that takes you to
the level exit.
