A sub-species of Bullet Bills? Is that confirmed or just speculation? To me, it seems that Giras are actually Bullet Bills, just like Pakkun Flowers are actually Piranha Plants and Chibibos are possibly Goombas (most enemies' names in Super Mario Land still had Japanese names even in the American version, which would explain the name "Gira").

According to The Mushroom Kingdom, the Japanese name for Bullet Bill is indeed "Kirā". It's only a small step from K to G in Japanese, just a voicing mark. This is most likely the Japanese name, untranslated. - Cobold (talk · contribs) 14:34, 1 March 2008 (EST)
I think it's a great idea to merge, but there had better be something on the Bullet Bill page that mentions that "the official name for the ones in this game are Gira" or something like that. People sometimes tend to overlook stuff like that. BLOC PARTIER.
