Unibo

Gordos are a species of enemy in the Kirby series that resemble sea urchins. In Super Mario Land 2: 6 Golden Coins, Gordo appeared as a normal enemy inhabiting flying and swimming areas. Much like in the Kirby series, Gordos were nearly indestructible, only being killed by a Star or Koopa Shell, but contradicted their role in Kirby by moving up and down when approached, accompanied by the widening of their usually-bored eyes. (In the Kirby series, Gordo's eyes are perpetually open, and a few icy rocks from Frozen Kirby can kill them, along with 10 hammerings from Hammer Kirby.) They appear once again in Super Smash Bros. Brawl, acting as one of the enemies King Dedede can toss when using Waddle Dee Toss. Sometimes, instead of a Waddle Dee, King Dedede will rarely pick up a Gordo and toss it instead. Apparently, it will continue to roam around the stage after it is been thrown. It also appears during King Dedede's Final Smash attack, Waddle Dee Army, reprising its role from Waddle Dee Toss. However, it appears to be much stronger than the Gordos from Waddle Dee Toss.

A Gordo also appears in Super Smash Bros. Brawl as a sticker.

Trophy Information from Super Smash Bros. Brawl
''A creature that sits in one place and doesn't even try to move. They won't even budge if Kirby tries to inhale them--they're the definitive obstacle. In addition, they're covered in spikes, so they damage whoever touches them. They're found stopped in groups, blocking narrow passageways, etc. Nothing's harder to get by than an encampment of Gordos.''
