Dropped Star
A Recoil Star (often just referred to as a Star) is an object that appears in several games in the Kirby series. It resembles a small Warp Star, or a stationary Star Bullet, and serves as the primary means for Kirby to attack a Boss or Mid-Boss without the help of a Copy Ability.
Appearances and Function
Recoil stars were first seen in Kirby's Dream Land, and have since reappeared in every main series Kirby title. They appear whenever a Boss or Mid-Boss performs an attack that makes hard contact with a surface - usually a floor - or may appear after a strong energy-based attack is executed. The most famous example of this is when King Dedede uses his Super Dedede Jump attack, which causes a recoil star to appear on each side of him when he lands.
Once they've appeared, recoil stars only last a few seconds at most before disappearing. Kirby has that time to Inhale them, and spit them back out as Star Bullets to do damage to his opponent (swallowing them does nothing). Recoil stars can come in several sizes, with the larger ones dealing more damage. They are especially potent if Kirby inhales multiple stars at once before spitting them back out.
Recoil stars may also appear in mid-air, where they will either stay afloat, or immediately fall to the ground, depending on the Boss being fought. Recoil stars do not do damage to Kirby if he touches them, nor do they hinder him in any way.
