This is the page about the time machine of Mermaid Man and Barnacle Boy. For other uses, see Time Machine (disambiguation).

The Time Machine is a machine that belongs to Mermaid Man and Barnacle Boy. It first appeared in the episode "Back to the Past." The Time Machine also appears in the short, "Lessons Learned."


The Time Machine is a large light blue machine with a large, yellow sign reading "Time Travel" in large magenta letters. Out of the top on both sides, there are red coils with light bulbs at the end. The words "Date" and "Location" are side-by-side at the top of the machine. Many multi-colored buttons (that do nothing) are seen at the lower end of the time machine, with a small radiator fan above.


Patrick, who is quite stupid, puts a quarter inside a coin slot and claims he lost his quarter, which sends SpongeBob, Mermaid Man, Barnacle Boy, and Patrick himself, into the past. It is seen again, where SpongeBob and Patrick use it to go into the past a second time. At the end of the episode, it is seen that a lot of the time machines go into the past. According to Barnacle Boy, going through time is so dangerous, he and Mermaid Man choose to leave it alone.
