On easy mode, there is a much easier way to get this achievement, without needing combos or any other such move combination.
You need to get to chapter three, and have completed the four mansions in the story-based quest. I recommend doing the bottom-right mansion last, so you're near the save point for this achievement.
You'll want Fidget's electrical attack selected. Go up one room from the save point outside the bottom-right mansion in The Sorrowing Meadow, then go up one room. Now hold the B button, so that Fidget's electric attack is continuous. Just move up, through the room, by continuously jumping to avoid enemies, still holding B, until you get to two step-like cliff-hangs on the right side of the screen. You'll get a zombie-spawning phantom enemy attacking you, and there will also be a bug-spawning hive above you. Fidget's electric attack will home in on multiple enemies, causing your combo meter to start raising VERY quickly. Now just continue to hold B, continuing to use Fidget's electric attack, and continue just jumping above enemies until the achievement pops. My explanations aren't very good, so I've done a video to describe this method, which you can see below:
