Big Urchins (formerly known as Mega Urchins) are enemies in New Super Mario Bros. Wii. They are a larger sub-species of Urchins. Big Urchins are giant Urchins with fat cheeks, HUGE yellow-orange spikes and eyes that are always staring at the player. They only appear in World 4. A Mega Urchin can be considered more dangerous than their smaller sub-species. They float up and down at the surface of the water; their eyes staring at the player. If the player comes in contact with them, he will take damage. Big Urchins, like any other large enemy, are much harder to avoid than regular Urchins, and jumping over them must be done with caution or the player loses a form or dies at small form. Mega Urchins are nearly invincible enemies. Unlike Urchins, an iceball or fireball does nothing to them. Big Urchins can only be defeated if touched with the Starman's invincibility. Big Urchins also reappear in Super Smash Bros. For Nintendo 3DS and Wii U as stage hazards on the stage, Mushroom Kingdom U. They will randomly spawn on a Water Spout. Players who touch them will take Damage. The Big Urchin also has its own Trophy in the game.

And the friendly looking Big Urchins have the sharpest spikes. They're also, you know, huge. They probably have to be careful not to poke each other while they wait for Mario.
