Drop is an enemy from Kirby 64: The Crystal Shards. It appears to be a water blob with a red sphere inside its transparent body. This is believed to be its heart or brain. It lives among caves hanging on the ceilings and then drops down when Kirby is near. Drops also can grow slightly for a short time.
When over Kirby's head, the the Drop will collapse into water. This is similar to the Sandman because when it is on the ground, it grows taller then shrinks smaller again. A mini-boss battle in Neo Star Stage 2 features a fight against several Drops, rather than a giant Drop, since there is no giant Drop.
