Urchins are little purple balls with yellow/orange spikes all around them. They have two black-colored eyes and puffy lips like the Cheep Cheep. They also have several dark purple spots around them. When the player passes them, they'll turn to look at them.
Urchins don't attack the player in any way, so the player must just dodge them. They'll either stay in place or move around, making it hard for the player to avoid them. They're always found underwater, though in some cases, they're found in floating water bubbles (such as in Red Lava, the last level they appear in).
Urchins can be killed in many ways, like shooting a fireball at them or using a Hammer Suit. Though, unlike other enemies, when they're hit by an iceball, they'll quickly break out, then fall down, knocked out.
