Galoomba
During the Koopa Troop's invasion of Dinosaur Land in the game Super Mario World, Goombas known as Kuribon were deployed in large numbers. However, these mushrooms did not appear in masswith Koopa Troopas filling the role of common soldiers seen in the field. Interestingly, while some Kuribon were stationed in certain locations as guards, others were dropped from the sky in droves. These Kuribon would either parachuting from above, or float down in bubbles (which would burst upon coming into contact with any object). The former variety assumed the name "Paragoomba", while Kuribon with wings were called "Winged Goombas".
In the Super Mario World remake, Super Mario Advance 2, after the player had beaten the Special World and found all of the exits, Kuribon turned yellow, wore sunglasses, and were cheerful-looking.
The Goombas that appeared in Super Mario World were dramatically different than those seen in previous games; they were even given a different name in the Japanese version of the game (Kuribon), seemingly rendering them a sub-species in Japan. Although these creatures walked in straight paths to attack, like previous Goombas, these new baddies did not look the older ones. These Kuribon did not have mushroom-shaped, but spherical heads; they also lacked a stem: their two feet were attached directly to the bottom of the head. As such, they resembled angry chestnuts more than scowling mushrooms.
These "round" Kuribon were also much more resilient than previous Goombas; only the powerful Spin Jump could destroy a Kuribon in one hit. Both Yoshi's eating attack and a fireball strike could transform a Kuribon into a gold coin. A normal jump would only flip the creature over, rendering it immobile. Interestingly, Mario or Luigi could actually pick up an immobile Kuribon and kick the fungus at other enemies to destroy them, however the immobile Kuribon would eventually resuscitate itself, and hurt Mario upon being revived (if the creature was not thrown in enough time). The same thing happens with shelled enemies in Super Mario World and in previous Mario titles.
