The cactus is a sign of protection and kids are naive and vulnerable and need protection. A monster into a cactus suit would not have made much sense in my vision of things. SANDy and her friends zip themselves into cactus suits because they think the world is a cold and scary place, and they need some protection to face it.
The cactus is the conserver of water, and water means life. The Cactus Friends for me are the representation of life, of being fragile and strong at the same time‚Ä¶ and pure like water ‚Äì Simone Legno
