SpongeBob SquarePants

The programme is a double bill featuring SpongeBob and Patrick as they view a previously unseen Mermaid Man episode. During the screening, Mermaid Man grows wary of the Dirty Bubble and his companions loitering near the library. The lost footage reveals the hero’s suspicion.

Back to the Past/The Bad Guy Club for Villains is presented as a double‑bill episode within its series. Classified as a programme rather than a full‑length film, it falls under the episode genre and is listed simply as an episode of the larger show. The title suggests a two‑part format, pairing distinct segments under a single broadcast slot. In the first segment, SpongeBob and Patrick settle down to view a previously unaired episode of Mermaid Man. While the duo watches, the titular superhero grows increasingly wary of the Dirty Bubble and the Bubble’s companions, who are spotted lingering near the local library. The narrative centres on Mermaid Man’s suspicion of these characters as they congregate in that particular location. The double‑bill structure allows the two storylines to unfold back‑to‑back, giving viewers a concise yet complete experience. The library setting provides the backdrop for the superhero’s doubts, while SpongeBob and Patrick’s viewing session frames the entire episode. Both parts are tied together by the common theme of characters confronting unexpected behaviour in familiar surroundings, delivering a compact and self‑contained adventure.
