Holy Cacti Batman, that thing looks like it can hold 200 gallons of water? That’s right it can. Holy Cacti Batman that Saguaro looks like it takes 10 years just to grow an arm? That’s right Robin. But you talk like you’re on TV or something. THIS IS REAL LIFE! Those are real and yes they can absorb a massive amount of water because they are succulent stems. (R) Batman what’s a SUCCULENT again, I forgot, I think these undies are TOO tight.? Boy wonder indeed. A SUCCULENT is a fleshy stem that is able to hold water.
