Cleistocactus strausii
As a houseplant, the Silver Torch cactus is an easy to take care of so long as over-watering is avoided. To naturally simulate the porous effects of the sand in its native habitat, it's important to ensure that excess water will not pool in the soil, causing the roots to become water logged.
This plant’s native habitat does not have winter, but when temperatures drop to the low twenties, it can exhibit signs of tip frost. 
The Silver Torch cactus is most susceptible to 
mealybugs 
and spider mite.
Crayon Shin-chan: My Moving Story! Cactus Large Attack!
They decided to defeat the killer cactus using water. But there was shortage of water in the city. 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.
