Bikini Bottom Adventures is a live-action webseries created by William Leonard, and produced by William Underscore Productions Ltd. It is an absurdist parody/celebration of the plush-toy video artform.

There is a plot, and there is no plot. SpongeBob, Patrick, and Squidward live in Bikini Bottom, and spend most of their time doing nothing. Occasionally, things happen. SpongeBob, Patrick, and Squidward observe things happening in Bikini Bottom and react to them. Sometimes they do not react to them. Sometimes these things are dangerous. Sometimes the characters themselves are the danger. SpongeBob, Patrick, and Squidward do not realize they are plush toys and that this is not Bikini Bottom and that they are in great danger. They will realize soon. SpongeBob, Patrick, and Squidward have lots of fun in Bikini Bottom.

The show began on January 16, 2017. All episodes are improvised, filmed, and edited on location in Bikini Bottom. All episodes are released on the Bikini Bottom Adventures YouTube channel.
