The ocean. It contains many a thing, but the one thing it is absolutely brimming with is Facts. In these comics, you will learn many such facts, all of which are 100% certifiably true and accurate. My brother is a marine biologist, so of course I am at the forefront of the sea sciences.
If you would like to examine the Facts in higher-resolution detail, as all people of Science should, you can find these comics in the shop. There are also some extra mermid comics here which may or may not also be Facts.
