Cleistocactus strausii
The cactus prefers free draining soils, strong sunlight, but not high temperatures — in fact it can withstand hard frosts down to -10 °C. In its natural habitat it receives plenty of water during the summer, but almost none over the winter. In cultivation, watering too much in winter often leads to root rot.

At the suggestion of Carolina and Francisca, they decided to use the water of the water supply tank on Chichideka mountain. The Mayor was again opposed to use the water from the tank, but had to give up this time. He let out his anger on Sumaho-chan. Hiroshi's plan was to inject water into a playing balloon called "Sabo-chan", and throw it at the Queen Cactus.
