Shroob-omb

A Shroob-omb is a giant purple Shroob Bob-omb used by the Support Shroobs during their battle with the Mario Bros. of past and present. The Support Shroobs would toss the Shroob-omb at the Mario Bros., engulfing the heroes in an unavoidable explosion. After the explosion, another Shroob-omb would be dropped into the battlefield by a Shroob UFO. Shroob-ombs have extremely high defense, meaning it is almost impossible to directly destroy these massive bomb creatures.

Only three Support Shroobs are needed to lift one Shroob-omb effectively, indicating the bomb is extremely light. In fact, even two Support Shroobs can lift the Shroob-omb if one of the Shroobs is destroyed, although the two remaining Support Shroobs will flash red under the stress. Ultimately, if two Support Shroobs are destroyed, the Shroob-omb will prove too heavy for the sole remaining Shroob. This last Support Shroob will be crushed and destroyed under the weight, and the Shroob-omb will roll off, either into the Mario Bros. (if the back Support Shroob remained) or Commander Shroob (if the front one remained). The middle one is random, but is mostly towards the Mario Bros.

Bob-ulk, a species of Bob-Omb from Paper Mario: The Thousand-Year Door bears a resemblance to Shroob-omb.
