From the Super Mario Wiki
Bulky Bob-ombs are massive pink Bob-ombs in Paper Mario: The Thousand-Year Door. In battle, they utilize a series of stat-raising moves before finally exploding. The explosion cannot be guarded or superguarded.
A Bulky Bob-omb follows this pattern of moves:
Hitting the Bulky Bob-omb at any time with a fire, lightning or explosive attack (except Clock Out) immediately causes it to explode, dealing two damage plus any accrued boosts to Mario, his partner, and all other enemies. The explosion causes other Bulky Bob-ombs to explode as well.
They also appear as part of the audience (where they take up two seats), and may blow up and knock away everyone around them as well as scaring away any Punies.
Stopping a Bulky Bob-omb in time halts its attack pattern, potentially allowing the defense buff to wear off before it boosts its damage and charges, or allowing both the defense and power boosts to wear off before it charges and self-destructs. Freezing it also prevents further attack progression, and also puts out its fuse at the same time, forcing it to spend a turn reigniting it. The fuse timer and attack pattern do not reset however.
