Cactopode

Start on good hold at head height, with feet on small rail under the overhang. Slap right hand to sloper and tread straight up.

"Confusion arises over the plural of cactus because its original pluralform (cacti) derives from Latin and native English speakers are drawn to cactuses, which adheres to the standard ruling for forming plurals. Both cactuses and cacti are acceptable. Of note, cacti is the more common plural."-grammar-monster.com/plurals…
