The bubble pear split off from the bubble cactus. It has become smaller in order to conserve energy. Other changes that happened during its evolution include larger bubbles than its ancestor, so that the spores can spread out more. They also have shorter and thicker branches which helps them retain more water. They reproduce the same way the bubble cactus reproduces, but do it much more frequently than their ancestor.
Since they are also found in the Huggs-Yokto Savanna, they gain more water from the ground than their ancestor. However, the most unique evolution is that the walls of the hydrogen bubbles became thicker and produce sugars and other nutrients. However, this causes the bubble pear to be more commonly eaten than the bubble cactus. One common consumer of the bubble pear is the sailbacked bearhog plent.
