Role in series
SpongeBob and Patrick go get a couple of Mermaid Man & Barnacle Boy comic books, the former having ditched school to get one. Fortunately for them, they are able to get their comic books and get them signed by Mermaid Man and Barnacle Boy themselves.
SpongeBob and Squidward are looking at the CCTV footage to find out where the Krabby Patty secret formula has gone and one part of the footage shows Bubble Bass reading a Mermaid Man & Barnacle Boy comic with an advertisement for the invisible helmet Plankton is wearing a bit earlier in the episode.
