Irrigonias are an artificial species of sentient, ambulatory plants.
Irrigonias are plants with a large sponge-like stem from which small roots stem. Their single flower has an expressive face on it, and the roots are mobile, acting like tentacles. This allows the Irrigonia to move about.
Irrigonias were designed by Professor Van Herb for the Center of Experimental Biofloridology as a help to humanitarian missions during droughts, as they are very good at finding and storing water, which they can then release on cue if their leaves are twisted like faucets. The first-ever Irrigonia was Petronilla the Irrigonia.
Behind the scenes
Irrigonias were first seen in the 2003 story The Thirsty Monsters.
