SpongeBob SquarePants

In “The Lost Mattress”, SpongeBob discards Mr Krabs’ former mattress, the one in which he stored his cash. In “Krabs vs. Plankton”, Plankton takes a major tumble and subsequently files a lawsuit against the Krusty Krab for the resulting damage.

The Lost Mattress/Krabs vs. Plankton is a programme presented in the form of an episode. Classified under the episode genre, it brings together two separate story arcs under a single banner, linking the events of ‘The Lost Mattress’ with those of ‘Krabs vs. Plankton’ in one continuous viewing experience. In the first segment, titled ‘The Lost Mattress’, SpongeBob decides to discard Mr Krabs' old mattress – the very piece of furniture that had long served as the repository for all of Krabs' money. By throwing it away, SpongeBob unintentionally removes the physical container that held the crab's entire fortune, setting the plot in motion. The second storyline, known as ‘Krabs vs. Plankton’, follows Plankton after he suffers a slip. In response to the mishap, Plankton files a lawsuit against The Krusty Krab, seeking compensation for the damages he claims to have incurred. This legal action pits him directly against the restaurant owned by Mr Krabs. Together these two parts illustrate a chain of unintended consequences: the disposal of the money‑filled mattress and the subsequent legal dispute triggered by Plankton's accident. Both narratives remain confined within the same programme, linking the characters' financial mishaps and courtroom clash in a concise, episodic format that ties the events together.
