Sea cacti,[1] also described as sea urchins[2] and spiky plants,[3] are an aquatic species of Neuron that lives in the oceans of Yoshi's Island. They appear only in Yoshi's Story, where they appear in only three levels: Neuron Jungle, Lots O'Jelly Fish, and Lots O'Fish. Sea cacti wriggle their bodies back and forth, and they cannot be defeated by any means; if a Yoshi tries to throw an egg at one, it harmlessly ricochets off the sea cactus. Sea cacti have spikes on the upper half of their bodies, meaning if a Yoshi collides with one, the Yoshi takes some damage. Sea cacti also can hang off ceilings, and if a Yoshi encounters one, it wriggles faster and detaches from the ceiling. This happens only in Neuron Jungle, however, as sea cacti are out of water; in levels where an upside-down sea cactus is in water, it simply stays put.

Sea cacti come in three sizes: big, medium, and small. Sea cacti also have 12 possible color combinations, ranging from orange to pink, making a total of 36 possible sea cactus varieties. Additionally, if a Yoshi walks far enough for a sea cactus to go offscreen, it changes color and size when the player returns.[4] Sea cacti are often seen in large groups. Sea cacti are able to survive outside water, but the only time they are seen on dry land is near a body of water.
