This achievement requires that you destroy 3 or more inflatables in a single shot and is most easily obtainable on Hotel Level 17. First, arch the Shark from the start over the stack of two inflatable blocks landing before the cluster of mines. Then dive down to hit the sprayfish, which will launch the ball into the mines. Then launch your Shark at full power into the upper entrance of the piping. This will launch your Shark through all three inflatables on the level, unlocking the achievement.
Alternative Method 1: Hotel Level 8: Right at the start, fire the shark at full speed to the right, towards the middle of the closest orange pillar. If done right, the tall, thin inflatables can pop when hitting the water of if the mine explodes. This shot is more difficult to pull off that the first method. Thanks to habs14 for the method.
Alternative Method 2: You can also attempt this achievement earlier in the game on Japan Level 14, however, that level is much more tricky. Thanks to slafferty for the tip.
