They are simple cottage-type log cabins with a shingled roof, with the walls being made of logs. The bottom of the house is made of stones cemented together.
In the episode "Bucket Sweet Bucket," Plankton decides to let SpongeBob and Patrick paint the Chum Bucket for him, and Squidward thinks they are doing it wrong so he decides to help. Squidward attempts to paint fancy paintings of himself on the Chum Bucket, but Plankton comes by and says that it's all wrong. Plankton then repaints the Chum Bucket into a picture of a Log Cabin, much to Squidward's disappointment. The Log Cabin picture doesn't appear after that.
- When Plankton paints the Log Cabin, it is in different colors of paint. However, at first, the color is only blue.
- It is unknown how Plankton goes down because he is only seen going up.
