Soul Bubble

The Soul Bubble appeared in 2005 video game called Mario & Luigi: Partners in Time. A Soul Bubble is a stronger version of the Love Bubble encountered in Shroob Castle during the events of Mario & Luigi: Partners in Time. A Soul Bubble is similar to a Love Bubble, except its body is cream-colored, and its crossed out eyes are green.

Being a stronger variant, Soul Bubbles have the same attacks as Love Bubbles, except they attack incredibly fast and are much more powerful. Also, while the Love Bubble always circles the brothers a set number of times during its homing attack, the Soul Bubble's amount before attacking varies. Soul Bubbles can still heal other enemies in battle, just as the Love Bubbles. They can, however, heal more HP than the Love Bubble, which is half of the damage inflicted to them, and also revive enemies that were previously defeated, much like Elite Troopeas and Scaratroopeas from Mario & Luigi: Superstar Saga.
