In "Swamp Mates", The Chief alerts the G.O.O.F.S. (Guild of Obsessive Fans) about Hoodoo Guru the voodoo villain, who has kidnapped Wonder Whale. Bubble Bass is especially angry about this and vows to defeat Hoodoo Guru and save Wonder Whale.
Bubble Bass and Patrick got lost in a swamp, where they spotted a mysterious cloaked figure, running away with the Wonder Whale action figure. Bubble Bass and Patrick chased after him.
When Bubble Bass finally cornered the mysterious figure, he fell into the latter's trap. The cloaked figure revealed himself to be Hoodoo Guru and showed him the Wonder Whale action figure he stole. Hoodoo announced that he stole the action figure so that he could complete his collection of other stolen action figures.
Bubble Bass and Patrick found out the net they were trapped in was made out of spaghetti noodles and ate their way out, landing themselves on Hoodoo and crushing him. While Hoodoo lied there, incapacitated, Bubble Bass took his toy back. Hoodoo used a voodoo doll of Patrick to control Patrick to make him attack Bubble Bass, knocking the Wonder Whale toy out of his hands and giving it back to Hoodoo. However, Hoodoo had a bit too much fun with the voodoo doll and accidentally made Patrick throw Bubble Bass back at him, knocking him out cold. Bubble Bass and Patrick escaped with the Wonder Whale toy.
Bubble Bass sailed the brine swamp, using Patrick as a raft but then a now conscious Hoodoo started chasing them, riding a boat with the Swamp Natives. Bubble Bass warded Hoodoo and the Natives off, saying that he and Patrick were armed with the power of reluctant friendship. Hoodoo and the Natives cowered in fear and drove off. Bubble Bass thought it was because of his threat, only to realize it was because they were approaching a waterfall. Bubble Bass and Patrick noticed the waterfall all too late and they both plummetted to their dooms.
