Rainbow Route

Rainbow Route, previously refered as Kirby's Hub Room, is a location in the game Kirby & the Amazing Mirror, serving as the first stage for said game. It also makes certain appearances within the Super Smash Flash series.

In Super Smash Flash
In Super Smash Flash, Rainbow Route was credited as Kirby's Hub Room and is the place where Target Test takes place. The stage is composed of tiles from the Rainbow Route, but a lot mor simplistic. All characters have access to this stage when palying thrugh the Target Test, but each character has a different arrangement and position for the targets.

In Super Smash Flash 2
Rainbow Route once again appears in Super Smash Flash 2, but this time as a full fledged stage. Due to the large number of platforms and walking space, this stage can be very difficult to play on. For example, most projectiles won't work well in this stage. The main focus on this stage appears to be the blue platform in the middle below the the golden mirror that served as the entrance to the Mirror World in Kirby & the Amazing Mirror.

It should be noted that for its appearance in Super Smash Flash 2, Rainbow Route once again uses it's original tiles, albeit revamped this time.

Overview and origin
Rainbow Route is located at the heart of the Mirror World. It connects to each of the levels that Kirby must enter to find the Mirror Shards. It begins as a simple grassland, but the scenery changes depending on where it's located, such as having a mountainous terrain when approaching Mustard Mountain, and pine forests surrounding Carrot Castle. Being the first level, the earlier parts of Rainbow Route do not have many challenges and is overall easy to venture through. As Kirby's quest progresses further, he moves to harder and more diverse parts of Rainbow Route, which have more complex puzzles and a wider array of enemies and impediments. The only place Rainbow Route does not come in direct contact with is the final level, Candy Constellation.

Rainbow Route is also the place where Kirby first comes face-to-face with his Mirror World counterpart, Shadow Kirby.

Music
