Green Greens (グリーングリーンズ) is a starting stage in Super Smash Bros. Melee and must be unlocked in Super Smash Bros. Brawl. It is also Kirby's home stage, and where the player faces him and his teammates in All-Star mode on this stage.
 Stage Description
The stage is made up of three floating islands. The island in the middle is the largest. There are two floating platforms over the middle island. The tree, Whispy Woods, in the middle of the middle island will occasionally blow gales of wind in a certain direction to disrupt the fight. Between the islands are blocks that stack up. Combatants can break the blocks by attacking them; hitting a bomb block causes an explosion in the vicinity, dealing heavy knockback and damage. The blocks will rebuild often after they are destroyed. Bomb blocks do 22% damage and have high knockback. The two islands to the left and right are somewhat small compared to middle island, and are usually where most of the fighting occurs.
Also, Whispy Woods will shake and let out apples from the tree. If players are on the middle section when this occurs, they will be damaged by them. Once on the ground, the apples can be one of two types of item: that which picked up and thrown at enemies, or a food item used to heal.
 Tournament legality
Green Greens is banned in tournaments in both Melee and Brawl, though older rulesets for Melee did allow the stage to be used; the reason for its banning is due to its overabundance of opportunities at camping. The bomb blocks can also easily disrupt matches, and in Brawl, their knockback is enough to allow for KOs. The side blast lines are also abnormally close to the platforms, allowing for early KOs, and the tower of blocks allows for wall infinites, such as shine infinites by Fox and chain throws by King Dedede.
Green Greens is the first level of Kirby's Dream Land. In Kirby's Dream Land star blocks are common small obstacles that could be used as a weapon or be destroyed and have appeared in numerous Kirby games ever since. One room of Kirby Super Star's The Great Cave Offensive features falling stars that turn into blocks. The falling stars can also cause damage if hit. The blocks also keep stacking up and can be destroyed. There are also star blocks in Kirby 64. On both sides of this stage there are falling blocks, which is likely a reference to the falling stars in The Great Cave Offensive. Unlike the falling stars in Kirby Super Star the falling blocks don't damage players. The design of the star blocks resemble the star blocks in Kirby 64. In Kirby's Adventure there are bomb blocks that explode when hit and cause a chain reaction to certain blocks. In Kirby Super Star the blocks are used in the same manner. The bomb blocks in this stage resemble the bomb blocks in Kirby Super Star, but the bombs don't cause a chain reaction; they just explode.
In Kirby's Dream Land the first boss is Whispy Woods, who is an apple tree. Whispy Woods has also been the first boss in Kirby Super Star's Spring Breeze. In this stage Whispy Woods resembles the Kirby Super Star version of him. One of the attacks that Whispy Woods uses is he sometimes will blow out puffs of air that would cause damage. In this stage Whispy Woods blows out air, but this does not cause damage. Another one of Whispy Woods' attacks is dropping apples that cause damage when hit. Kirby can also suck in the apples and spit them out at Whispy Woods to defeat him. In Kirby 64 Whispy Woods shakes apple off of him instead of them just dropping. In this stage Whispy Woods shakes the apples from him in a similar fashion to how he did it in Kirby 64. Just like in the Kirby games they cause damage if the player is hit by the apple. At the end of Kirby Super Star's Dyna Blade Kirby sees a nest full of noisy and hungry baby birds. He then takes the birds to Whispy Woods and knocks apples out of him to feed them. In this stage, the apples can be used as food to refill the player's health. In Kirby 64's first world there are paths that the player has to follow. The path that is seen on this stage resembles the path in Kirby 64's first world. 
The music used for Green Greens is a mix of the first level of Kirby's Dream Land and the track used for the ending of Milky Way Wishes of Kirby Super Star.  The Green Greens part of the track also sounds very similar to The Great Cave Offensive's track Crystal Field and Mystery Paradise from Kirby Super Star.
