The Plumber's Log is an unseen log book of Mario's that he uses to record his adventures throughout the animated segments of The Super Mario Bros. Super Show!. It's an obvious pun on Star Trek's "Captain's Log".
At the beginning of every episode, Mario would quote (in a voiceover) a brief entry from his Plumber's Log, usually explaining where he and his friends had traveled to, why they were there, and what they were about to encounter.
Each Plumber's Log has its own numbered entry, although there does not appear to be any plausible or chronological order to them in regards to the order of the episodes.
Note: Each Plumber's Log entry is written the way Mario pronounces it. For instance, the Plumber's Log for the first episode is written as "1-0-1", because Mario actually says "one-oh-one", as opposed to "one-hundred and one". Also note that Mario always says "oh" in place of any zeros.
However, there are a few entry numbers that this rule does not apply to, usually because the number has an actual meaning (ie; the number is a year).
