Magic Vine
Magic Vines are essential and very consistent objects in the Mario franchise. They first appeared in Super Mario Bros., and remain dormant inside blocks until their block is struck. They then grow into a tall vine and allow Mario or Luigi to access new heights.
In Super Mario Bros. 2, the vines are already in the level and sometimes don't even have anything to grow from. In Super Mario Bros. 3, they match the color scheme of the world they are located in; brown for World 2, green for Worlds 3 and 4, blue for World 5, and white for World 6. However, in New Super Mario Bros. all Magic Vines are green.
In Super Mario World, some vines grow toward breakable blocks. If Mario removes the blocks the vine can continue rising, making shortcuts available.
They next appeared in New Super Mario Bros. However, the direction the vine grows depends on whether Mario or Luigi hits the block containing the vine from the bottom, or Ground Pounds it from the top.
In Super Paper Mario, Magic Vines took on a more simplistic appearance; simply a single black line zig-zagging up until it hit something. Though they themselves were in 2-D, this was their first appearance in a 3-D game, since New Super Mario Bros.
In Super Mario Galaxy, vines once again appears (this is their first 3-D appearance). The vines usually appear when a Piranha Plant is defeated, and unlike in other games, they don't appear when a block is hit.
It is interesting to note that most Magic Vines have Piranha Plants as their heads while they are growing. The head disappears when the vine is fully grown. Like other Piranha Plants, the head will change into a Jumping Pumpkin Plant in Super Mario World, after the player completes Funky.
