Although these creatures' attack pattern greatly resembles that of the Chute Leech, Octroll can both jump much higher and cause a bit more damage. These creatures are larger than Samus. When destroyed, they nearly always yield large energy units. They are encountered in only one section of SR388. It is unknown if the X Parasites saw the Octroll species as a potential host, as Samus did not encounter any Octroll-X in Metroid Fusion.
"When Samus comes close, they fall fluttering downward."
