In Super Mario Land 2: 6 Golden Coins, Unibō are Urchin-like enemies inhabiting flying and swimming areas. Unibō are nearly indestructible; they can be defeated by only a Star or Koopa Shell. They remain stationary until Mario comes near, at which point they will shake on the spot to make themselves harder to avoid. They reappear in Mario & Wario, slightly redesigned to look more like Urchins and their visible eyes removed (although they could be facing away from the screen). In addition, they now come in two varieties: those with blue bodies move vertically, and those with yellow bodies move horizontally. In addition, they no longer sleep and are contantly moving around.
A Gordo, which looks similar to a Unibō
The original appearance of Unibō is very similar to both Gordo from the Kirby series and Sea Urchins from the Zelda series.
