Super Happy Tree
Super Happy Tree (スーパーしあわせのツリー, Super Happy Tree), previously referred to as Yoshi's Island (ヨッシーアイランド, Yoshi Island), is a stage in Super Smash Bros., Super Smash Bros. Melee, and Super Smash Bros. Ultimate.
Visually, the stage looks like it's made of cardboard. The main platform is an open book, and as such it has a V shape instead of being completely flat. Over the main platform hover three soft platforms; the bottom two slightly slope inwards, while the top one is flat.
In the sky surrounding the main stage float three clouds, one on the left side and two on the right. After standing on a cloud for about four seconds it will disappear; this can be prevented by repeatedly jumping instead of standing continuously on it. Disappeared clouds reappear after seven more seconds. Message Blocks hover in the background above the clouds, but they have no gameplay effect.
When the player fights False Yoshi in The Great Maze, the stage resembles Yoshi’s Island (SSB), except the main platform is not shaped like an open book, and the colors and background are different.
In Ultimate, the side blast zones, especially the right blast zone, are moved inwards when the camera is set to "fixed". This includes Training Mode, where it is possible to position players close to the right blast zone, and set the camera to fixed, resulting in that player being KOd immediately upon closing the menu.
Ω form and Battlefield form
In Super Smash Bros. Ultimate, the main platform of the Ω form and Battlefield form is a completely flat version of the main platform of the normal form and is resized and reshaped to match Final Destination and Battlefield, respectively. The three soft platforms of the Battlefield form resemble the ones in the normal form.
If hazards are turned off in Ultimate, the clouds will never disappear.
This stage is loosely based on Yoshi's Story, in which Baby Bowser turns Yoshi's Island into a storybook and steals the Super Happy Tree. This causes the environment to be turned into various materials such as cardboard, yarn, and fabric. This stage is an amalgamation of the cardboard theme of the first level (Treasure Hunt), and the fabric and cloth theme of the second and third levels (Surprise!! and Rail Lift, respectively); however, the sky was colored blue in those levels, whereas, in this stage, the sky is light orange. The Super Happy Tree is also in the background of the main platform. Yoshi's Story also features clouds that can be used as platforms, some of which have to be activated by pressing a switch and disappear when the switch's timer runs out; however, their design is different from the ones in this stage.
Message Blocks appear in some Mario and Yoshi games, and give hints to the player when hit. Also from the Yoshi games are Goonies and Fly Guys where they appear as flying enemies. The aforementioned elements are also based on their designs from Yoshi's Story and are seen in the background.
The Super Happy Tree itself appears in the final level, Magma Castle, during the fight with Baby Bowser.
Super Happy Tree is banned in every appearance, primarily because the clouds can promote camping. In particular, the rightmost cloud is very far from the stage and is a very powerful camping spot; additionally, some characters such as Link in Smash 64 are unable to make it back to the stage from said cloud. The cloudless variant from Smash 64's single player is sometimes legal in doubles, but as it requires modifying the game, it is rarely seen outside of specialized rulesets (such as GENESIS 6).
