Normal

Brute force is fine.
Hit the blasters when they are exactly parallel (3 & 9 o'clock).
Hit the lower left blaster at 3 & 9 o'clock. Hit the upper blaster when it rotates to 10 & 4 o'clock, so it removes everything attached to the support on the lower right.
You will be given 4 blasters to get through this level. You only need 3 blasters to win. Drop the first blaster at 3 & 9 o'clock, then hit up on your D-pad to shoot it straight up. You will lose the second blaster. Carefully drop the third blaster only at 10 & 4 o'clock and remove the left side, and the fourth blaster at 2 & 8 o'clock to remove the right side.
Time your shot so the paint change bubble is the same color as the one you're shooting.
Same as 5. You might need to clean up a support or two manually at the end.
Aim to the right about 30 degrees. Clean through the entire right wall and as much of the ceiling as you can. You need to ricochet the off the wall and then ceiling to hit the paint bubble in the middle.
Ignore the planks. Clear off the support bubbles until you can get to the ceiling.
There are many ways to solve this. Brute force works fine. hit the bottom most blaster at an angle (10 & 4 or 2 & 8) when the other blasters are parallel (3 & 9) and drop the paint bubbles to clean up what remains.
Hit the bottom two blasters at an angle to open up the second tier of bubbles. If you can drop either the third or 4th blaster at 3 & 9, awesome. If not, just hit it at 3 & 9, and use the remaining blank bubbles to manually clean out the Chack'ns at the top.
The most important thing to do here is drop the planks. aim for the corner bubbles holding them up. Once those are out of the way, keep firing until you hit the Chack'ns in the matching colors.
A combination of brute force and careful timing will carry you through this stage. Your playable character will spend much of the time in a panicked state.
When you pop the yellow, orange and blue clusters, make sure the resulting paint bubbles are all the same color. I recommend blue. Fire one directly up. Fire the second one between the orange and yellow bubbles on the left, and the same on the right. Then pop the entire cluster.
Carefully peel off the paint bubbles on the left side one stripe at a time. If you don't have the right color, shoot directly up so the unneeded bubble bounces off the ceiling. You can easily hit the yellow bubble hanging off the ceiling with a paint bubble. Aim high and tear off as much as you can with each successive bubble until you can paint the last cluster including the orange bubble on the top right.
WIDE STAGE Dig until you open a blaster. Hit the blaster when it is parallel. Due to how wide the stage is, the blaster won't be able to extend all the way to both ends of the stage. If you hit the blaster on an angle, it is not the end of the world. Just be quick and dig your way to the top.

EX

Clear out the bottom of the hexagon. This will buy you some time to clean out the lower sides. Like endless mode, the less you need to move the pointer, the faster you can clean these out. Go up the sides until you can safely ricochet off the wall to clear out the top half of the stage. To reach the top half you want to be at around a 45 degree angle. Be careful not to get bubbles stuck on the planks creating more work for yourself.
Drop the star bubble with a yellow. Clean out the one blue bubble. Shoot the star bubble where the blue bubbles were so you hit all 4 remaining colors simultaneously.
Dig through the blanks until you can hit the paint bubbles. Clean off the top manually.
Hit the paint bubbles, even when they don't paint anything advantageous. Cleaning off the supports is more important.
🌶 [COME BACK TO THIS ONE]
TIP: Complete this level with the long pointer first before you try to 3 star it. First, get your character to stop panicking by shooting the diamond clusters of bubbles off the bottom row of rocks at the corners. Now shoot at a 30 degree angle, aiming directly to the left of the rock on the top row to hit the green Chack'n dead on. Do the same on the far right for the blue Chack'n. For the ones in the middle, imagine a straight line going through the cog wheels in the background. Draw a line through the center of those cog wheels to the pipes framing the stage—this spot is at the same level as the rocks in the bottom row. Drop your pointer to about 60 degrees to hit that spot. Shoot to the left. Your bubbles will bounce right until they hit the band of the release valve near the top right pipe—this spot is at the same level as the rocks in the top row. Then the bubbles will bounce off the ceiling to directly on top of the rocks in the top row. Keep shooting until you free orange Chack'n. Now rotate your pointer to the right and keep shooting until purple Chack'n is free.
Carefully peel off each paint bubble so they're all the same color. Paint the chack'ns the same color. You want to hit the rock in between the chack'ns to guarantee you'll paint two in the same burst. When they're all painted, hit the star bubble. There is almost no room for forgiveness in this stage so aim very carefully.
WIDE STAGE Time your shots to match the paint bubbles. It helps make clean up faster. Brute force should get you through the rest.
This stage has no room for error. If you mess up one of these blaster drops, restart. The idea is to drop one blaster at each of its different angles to remove all the bubbles from the inside of the rocks. You need one at 10 & 4 o'clock, one at 2 & 8 o'clock, and one 3 & 9 o'clock. If you mess this up, restart the level. There are three guide bubbles and three blasters. Imagine them labeled from left to right. Hit guide bubble 2 to knock it out of the way. Drop blaster 1 at 10 & 4 o'clock. Shoot this blaster in the space where guide bubble 2 was. Hit guide bubble 3 to knock it out of the way. Drop blaster 2 at 2 & 8 o'clock. Shoot this blaster in the space where the guide bubble 3 was. Angle your pointer to the right and drop blaster 3 at 3 & 9 o'clock. Angle your pointer to hit in between the rocks so you can remove the bubbles at the top inside the rocks. If you've managed to do this all in under 30 seconds, drop guide bubble 1 for a stage clear.
🌶 WIDE STAGE This stage is too wide for you to just brute force your way to the top. Clear what you can and peel off the paint bubbles one at a time to clean off what you cannot. It'll be tight.
