Unlockables: Boris (VS mode), Miniroon Knight costume, ??? Chack'n costume

Normal

Aim for the bubbles holding the planks up to drop the Chack'ns.
Beeline the paint line bubbles.
Hit the bubbles connecting the supports, only.
Aim carefully to hit the bubbles connecting the supports and drop the ghosts until you can pop the purple and yellow ones on the ceiling.
Aim directly at the lowest bomb on the Left. It will cascade explode all the other bombs and clear the level.
Brute force is fine.
Carefully drop and aim each bomb at the ghosts. If you have any left over, aim them straight up to deal with the triangular cluster of bubbles you will need to take care of manually.
Drop the paint bubbles in the lower corners and shoot them straight up at the cluster in the center. Keep digging until you hit the paint bubbles in the center. Finish off the top of the cluster with the paint bubbles from the upper corners.
Drop each bomb and shoot it at the cluster of ghosts until you can dig out both pink Chack'ns.
Do what you can to avoid putting orange on the field until you can remove the entire row at the very top. Hit the paint bubbles to clear out as much as possible, and clean up the rest manually.
Brute force is fine.
Try to use all the paint bubbles on one side to clear out as much of the center cluster as possible, then switch to the other color. Clean up the remainder manually.

Use the guide bubbles and aim with extreme caution.
Use the change bubbles to drop off sections near the ghosts. Work carefully around the ghosts until you can drop them all off.

EX

Carefully drop the bombs to blow up the ghosts. If any remain, aim with extreme caution to remove the left over normal bubbles.
Beeline the paint and paint line bubbles.
This is set up a lot like previous levels but is too wide to be manageable. The lower pairs of yellow and purple Chack'ns on the far left and far right can be ignored. Concentrate on getting the mid level blue and green chack'ns out, by shooting the long green and blue lines, and then up the chute if you can manage. This drops off the chack'ns which are otherwise not accessible. If you have the ricochet skills you can blow out the top layer of chutes and get the remaining 4 pairs of chack'ns that way. However, it is easier it just dig them out manually.
Beelining for the blasters is a safe bet. Keep shooting diagonally until the ghosts start dropping off.
This stage has no room for error. Get rid of the purple-blue purple row at the very bottom. Carefully drop off the yellow paint bubble and color the blue Chack'n yellow, then pop it. An orange paint bubble will drop off. Shoot that upward to color the lower three purple bubbles. Break the horizontal orange row, then the purple row. On the left side stage frame, count 2 rows of brickwork up from the Danger Line to ricochet a bubble to the orange paint bubble near the very top. Finally free the chack'n trapped between the rocks.

Prioritize hitting the purple paint line bubble on the right to clear the support, the orange one on the right to clear a line, the green one for the second support, and the pink and yellow ones at the very top. You can beeline the pink and yellow paint line bubbles but don’t forget about the support clusters.
Try to focus on the left side and shoot up along the diagonal until you get to the top. Be careful where you place the oranges until the third stripe is open.
Shoot carefully between the ghosts diagonally up to the left and right. The pinks in the thurd row from the top should drop most of the ghosts further below. Then clear out the top two rows.
