In Stage 1 of Endless Explosions, as your riding the hanging boat, carefully maneuver
it until you spot a key on the far left.
Grab it and go right, avoiding the cannon in the background, until you see the locked
door.
Open it, grab the invincible candy, and fly up to find the Sun Stone between the lava.
In the area with the moving platforms, make sure to grab the Ice ability.
Use it to cool the lava blocks on the far right.
Break them and enter the orange star door.
On the other side, try to cool the lava without breaking it so that you can send down the
chest without it falling into the pit.
Open it to find the Sun Stone.
When you spot a Wheelie going back and forth, take its power and go through the grate.
An enemy will start running in the background.
Use Wheel to race down with it.
Jump into the 3D Warp Star and destroy the enemy before it tosses the key into the lava.
Use the key on the locked door and, on the other side, open the chest for the Sun Stone.
In this same room, break the cracked block on the top left and work your way across the
path.
At the end is the Rare Keychain.
In Stage 2, make sure to come in with the Ice ability.
Above one of the pools of water in the first area are some lava blocks.
Carefully use ice to cool them off and break the blocks.
On the other side is the Rare Keychain.
You'll eventually see a Sun Stone in the background.
Continue swimming up until you reach a 3D Warp Star.
Take it into the background and swim back down to reach it.
In the horizontal swimming section with the eels, keep an eye out for the Stone ability
on the top left.
Make sure to keep it until you reach the bottom of the area.
On the left is a peg.
Drive it in with Stone and go through the orange star door that's revealed.
On the other side, you'll appear with dynamite in your hand.
Quickly drop it and fly to the other side.
Drive in all the pegs before the dynamite explodes in order to destroy the rock blocking
the way to the Sun Stone.
After you get the Hypernova ability, you'll see a cork that you can't reach.
Destroy the bomb block to the left of it in order to create a platform.
Suck up the cork in order to bring the chest to the foreground.
Inside is the Sun Stone.
Later on, one of the eels is blocking the way to the Sun Stone.
Suck him up and hit the switch in the background in order to access the stone.
In Stage 3, you'll eventually come across some cannons.
Jump inside the bottom one and aim it toward the slight left.
In the next cannon, aim again toward the slight left in order to be shot toward the Rare Keychain.
Once you're back in the main cannon, shoot straight up to break through a block and find
the Sun Stone.
Further along, you'll see dynamite in the background near a 3D Warp Star.
Before using it, jump on the platform pulley so you can access the dynamite.
Once you grab it, jump on the platform to raise the one in the foreground.
Return there and jump to the top right.
Use the dynamite on the blocks to reveal the Sun Stone.
During the wall crusher sequence, you'll find a thin, winding path.
Quickly navigate it so that you have time to enter the upper door at the end.
Simply pull the lever to access the Sun Stone.
In Stage 4, you'll come across a set of rocket platforms.
Use them to destroy the blocks in the background so that you have a clear path.
Use the 3D Warp Star at the end of the path to enter the background.
Press the switch to open the gate to the key.
Carry it all the way to the left end of the path and use it on the locked door.
There's a small hole that leads to a bomb block.
Destroy it to get to the Sun Stone.
In the area with cannons and bomb blocks, take the Archer ability.
One of the bomb blocks will create a platform were you can shoot another block.
Go through the hidden orange star door and complete the archery challenge in order to
get the Sun Stone.
During the shifting wall section, there's a door in mid-air at the very end.
Before taking it, destroy the cracked block on the bottom right.
Beneath it is the Rare Keychain.
After you get the Hypernova ability, you'll come to a falling lava section with a small
gap.
Float into that gap to find the Sun Stone.
The last Sun Stone cannot be missed as it appears after you defeat the mini-boss at
the end of the stage.
In Stage 5, you can find the first Sun Stone after defeating the first mini-boss.
In the background, break the bomb block and go through to open the chest.
Inside is the stone.
Defeating the second mini-boss leads to the second Sun Stone; quickly break all of the
blocks in order to get to the chest containing the stone.
After beating the third mini-boss, break the bomb block on the right to get to the chest
with the Sun Stone.
Do not jump into the 3D Warp Star leading to the last mini-boss.
Instead, fly above it to find another one and take that to a secret area.
Travel to the background and open the chest for the Rare Keychain.
And once again, after beating the final mini-boss, go to the background and open the chest for
the Sun Stone.
Stage 7 will be unlocked once you collect all of the Sun Stones in Endless Explosions.
In the stage, you'll come across two laser pole sections.
In the second one, stay close to the enemy holding a key in order to protect it from
falling debris, enemies, and to break bomb blocks that create platforms.
It will eventually reach the locked door and use the key on it.
Grab the Archer ability before going through.
Complete the archery challenges in order to gain the Sun Stone.
During one of the wall crusher sequences, you'll spot a line of stars leading up.
Follow them to find the Rare Keychain.
The last Sun Stone can be found after defeating the mini-boss.
It's in the chest after taking the teleporter.
