Soul Bubble

A Soul Bubble is a stronger relative of the Love Bubble encountered in Mario & Luigi: Partners in Time. The four Mario Bros. fought these while storming Shroob Castle, the Peach's Castle of the past after it was taken over by the Shroobs. A Soul Bubble is similar in appearance to a love bubble, except its body is cream-colored, and its X-ed out eyes are green.

Soul Bubbles have all the same attacks as Love Bubbles, except they attack much faster, making the attacks harder to dodge. 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 like the Love Bubbles. However, the yellow enemies heal more HP than their original relatives. Soul Bubbles can also revive other enemies that were defeated by Mario and Luigi.
