The SpongeBuddy Mania Yearbook is an annual pinned topic in the Nautical Nonsense subsection of the Forums. The yearbook serves a purpose of profiling members by including fields asking such things as their age, gender, and approximate location, as well as hobbies and favorite things. Despite this, participation in the Yearbook is voluntary. Members are also asked to post a picture of themselves, or, if they are camera-shy, to create a South Park version of themselves, in a Yearbook tradition that began in 2009. The Yearbook usually is conducted in April but its timing has been more unpredictable in recent years, with the 2012 Praisebook being released in July.
The Yearbook is traditionally published to the forums alongside another annual topic, the Praisebook.
