Vine
Beanstalks (sometimes called Vines) are used as ladders in the Mario games. They first appeared in Super Mario Bros. and came out of ? Blocks. When Mario or Luigi hit the blocks containing the Beanstalk, a Beanstalk would grow allowing Mario or Luigi to use it as a ladder. They also appeared in most platformer games.
The Beanstalk also appears in Hotel Mario. Luigi kicks a yellow ! block, and a giant vine comes out which Mario and Luigi climb to go to Lemmy's High-ate Regency Hotel.
A Beanstalk is also an item in Super Mario World 2: Yoshi's Island and Yoshi's Island DS, having a smaller head and smaller eyes in the latter game. Occasionally, when popping a ? Mark Cloud, Yoshi may uncover one of the seeds of these large, cheery plants. It then grows upwards at a very fast rate and produces ledge-like leaves while doing so. By hopping up its leaves, Yoshi can reach places otherwise inaccesible.
If the player is carrying an item such as a P-Switch, the stalk cannot be climbed normally. The player can kick the item up, start to climb the Beanstalk, and then hold the Y button again to catch the item coming down while climbing.
In New Super Mario Bros., beanstalks have the head of a Piranha Plant at the top of them.
