Without any suits or tanks, Samus will need to move the Beetom part way up the room, shake it off, and go back and farm multiple times. While the Beetom is near the top section, by the Rippers, shake the Beetom off, and re-grab it and ascend the shaft. Either use frozen Rippers as platforms, while shooting diagonally to prevent freezing the Beetom, or kill the Rippers before ascending. Be careful not to apply too many inputs after grabbing the Beetom in order to get to the top before it is shaken off.
