Beanstalk

Beanstalks 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 other games like Super Mario World where they were used the same.

A Beanstalk is also an item in Super Mario World 2: Yoshi's Island. 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.

They reappear in Yoshi's Island DS but look slightly different with smaller heads and eyes.
