Snake (Yoshi's Story)
Snakes are creatures that float in the air and can be used as moving platforms in Yoshi's Story. When a Yoshi steps on one, the Snake will start flying in the air. They are only encountered in Stage 3-1: Cloud Climb, in which they are found en masse.
There are two types of snakes: Green Snakes and Pink Snakes. When stepped on, both will play carnival-esque music, but the music is slightly different depending on the Snake and plays either forward or backwards, depending on the Snake's path.
 Green Snakes
Green Snakes are the first type of Snake that is encountered. When they are stepped on, the Snake will ceaselessly move diagonally in the direction it is facing. If a Yoshi were to jump and land on the Snake again, it would continue flying in the same direction. However, its incline would be inverted; for example, if it was originally going towards the top-right corner of the screen, it would then go towards the bottom-right corner. Green Snakes have good traction, and the only time a Yoshi should fear slipping off a Snake would be if the Snake were to pass behind an object that the Yoshi couldn't pass through. Also, once reaching the top of the stage, the Snake would continue to move out of the screen. Green Snakes come in handy when one wishes to pass through the air horizontally.
 Pink Snakes
Pink Snakes are the second type of Snake that is encountered, and they are much trickier to control. While re-touching a Green Snake would cause the Green Snake to change its incline, once a Pink Snake begins to ceaselessly move diagonally, re-touching it will make it change direction. Therefore, if a Pink Snake were to be moving towards the top-right corner of the screen, it would then go towards the top-left corner. At least from what is seen in Yoshi's Story, Pink Snakes are not known to ever go downwards. Pink Snakes are very slippery creatures; if a Yoshi were to stand still on one, the Yoshi would not rise or lower, but simply slip off of the Pink Snake. Therefore, to get anywhere whilst on a Pink Snake, a Yoshi would have to walk on the snake in the same direction that the Snake were going. Unfortunately, the Yoshi would have to re-jump onto the Snake when it changes direction; hence, it is quite difficult to move horizontally on a Pink Snake. Pink Snakes come in handy when one wishes to rise through the air vertically.
Should a Yoshi lose his Snake, he could always find a new one at the original spot it was found at. Otherwise, once a Snake moves, it never ever stops.
