|Catch Card #||N/A|
A humongous purple Bulky Bob-omb, Bob-ulk is the toughest Bob-omb in Paper Mario: The Thousand-Year Door. Like the Bulky Bob-omb, a Bob-ulk will charge up its defense and attack power before fatally self-destructing, causing a damage total of 16. Also like Bulky Bob-omb, if they are hit by a bomb or fire related attack or item, they'll instantly explode. Mario will still take a fair amount of damage, but this method is wise to use, especially if you're fighting four at one time. They are only found in the pit of 100 trials.
