Rubbery bulb

Rubbery bulbs, also described as bulbs , rubbery plants , plants , wiggly bulbs and green bulbs , are a species of plant appearing in the game Super Mario Galaxy and Super Mario Galaxy 2. They appear as green plants with a bulbous head and a thin, stretchy stem.

Super Mario Galaxy
In Super Mario Galaxy, rubbery bulbs appear in various galaxies, most notably the Good Egg Galaxy. If Mario or Luigi hit one with a spin, it will stretch in the opposite direction, hitting any enemy or obstacle in the way. If it fails to hit an obstacle or an enemy, it will come right back and hit the plumber, causing him to fall back and lose some Star Bits. If one is ground pounded or run over by an enemy such as a Boulder or a Chomp, it will become flattened and unusable for a short period of time.

Bulbs appear during the final fight with Bowser at Bowser's Galaxy Reactor. They are seen in the second phase of the final battle and are used as protection against Bowser's fireballs and to attack him.

Super Mario Galaxy 2
Bulbs reappear in Super Mario Galaxy 2. However, they are uncommon, only appearing in the Sky Station Galaxy, Freezy Flake Galaxy and Battle Belt Galaxy. They keep their same appearance and use from the previous game. This time, they are used to defeat certain enemies such as Prickly Piranha Plants and Silver Chomps. Bee Eater, a spiky variant, also makes an appearance.

Mario Party 10
In Mario Party 10, three small bulbs can be seen on a grassy field with two Lumas and a flower bed in the north-western part of the Rosalina Board. They are only decorative.
