Fireworks! - 10
Make 7 or mines explode consecutively.
First obtainable on Home Level 19. From the start, launch the Shark to the right destroying the inflatable block. This will cause the mine to roll down and destroy the other 5 mines, unlocking the achievement. Even though only 6 total mines are destroyed, the achievement unlocks.
You could get this on Japan Level 1 too, if you aim the shark with full force towards right
