Big Urchins (much like normal Urchins) are big purple balls with yellow/orange spikes all around them. They have two black-colored eyes, and puffy lips. They also have dark purple spots around them. They appear to be a little bit chubbier than the normal Urchin, as shown with their cheeks covering their eyes. When the player passes one of them, they'll turn to look at them.
Big Urchins act the exact same as the normal Urchin, but now have a bigger hitbox. They'll either stay in place or move around, and sometimes appear out of water. Unlike their smaller counterparts, Big Urchins can't be killed by most things. They're immune to fireballs, iceballs, and hammers, though they can be killed by a Super Star. This is used to hide some Star Coins, as you must be quick enough to save the Super Star and reach the Urchin.
