Freddi Fish 2: The Case of the Haunted Schoolhouse
Spongehead and Boss the Sharks are the secondary antagonists of Freddi Fish and the Case of the Missing Kelp Seeds and Freddi Fish 2: The Case of the Haunted Schoolhouse.
Prior to the game's start, the sharks had already stolen Grandma Grouper's Kelp Treasure as part of their plan to help the Squidfather grow kelp for himself. Because Spongehead hid the treasure, he left clue bottles in various locations, so he could find his way back to the treasure.
The sharks first appear after Freddi Fish and Luther find a message bottle that Spongehead hid and leave to the direction of the next bottle. Spongehead can't find the bottle and is afraid somebody else found it first. Boss tells him somebody already clearly did that and they got to find the bottle before they are severely punished.
When they still can't find the bottle, Boss gets mad at Spongehead for hiding those bottles everywhere and Spongehead explains why he did so. Since he "lost" the treasure, Boss forcibly takes his partner to the Squidfather as punishment.
When Squidfather learns they lost the treasure and Spongehead still can't remember where it was, Squidfather gets mad and spews ink everywhere. However this is enough to make Spongehead remember that he put the treasure inside the sunken ship, which calms down the Squidfather. The sharks leave to go retrieve the treasure.
The sharks arrive and find the treasure just as Freddi and Luther are about to take it with them. Boss tells the kids to hand it over, but Freddi refuses since the kelp seeds are for everyone. After the sharks explain why they need it, Freddi suggests they share the seeds so that everyone is happy. The shark like this idea and agree to the compromise and they leave to go tell the Squidfather the new plan they are going to do.
Prior to this game's start, Spongehead and Boss had been stealing the toys from the school guppies, so the Squidfather could play with them as he never had a toy to play with. The sharks achieved this by scaring the guppies as a ghost and stealing the toys while the guppies are outside the schoolhouse. When Freddi and Luther came to the Schoolhouse to solve the case, the sharks are unable to continue their plan due to the guppies remaining in the schoolhouse.
The sharks nearly steal Luther's Codfish Commando Action Figure, but Freddi and Luther manage to retrieve it, but the sharks (in costume) swear to steal the toy before leaving. As part of the costume got torn off by a piece of wood Freddi deduces that the ghost is just someone in a costume and plans on catching the phony ghost.
When the Squidfather discovers the sharks are unable to steal more toys for him because of Freddi and Luther, he threatens the sharks to get rid of the kids and Freddi and Luther or face consequences.
Later after Freddi and Luther gather four of the five items needed for their trap. The sharks warn Freddi and Luther if they keep snooping around the schoolhouse, the ghost will turn them into fish sticks. Freddi is not scared by these threats though Luther is. Boss says they warned them but the kids shouldn't say they told them before the sharks leave.
Once the trap is set, Freddi and Luther use Luther's action figure to lure the sharks to their trap. It works and right as the sharks try to steal the action figure, Freddi and Luther activate their trap and trap the sharks. Upon tearing off the costume, they discover the bag full of stolen toys.
After a talk between Freddi and Luther and the sharks, the sharks let Freddi and Luther return the toys they stole to the guppies, however Luther saw how much the Squidfather wanted to play a toy and gave the sharks his Codfish Commando Action Figure to give to the Squidfather, so that he will have at least one toy to play with.
