Lego and Animal Crossing seem like they would be a great fit. Depending on how you count there are almost (or more) than 500 villagers that appear in the video game series. One of which is named Octavian. In Animal Crossing he is known as a cranky octopus who is really into outer space and aliens. The octopus type of villager is one of the more rare types to visit, making Octavian rather special. This Lego Octavian is the creation of Dave Foreman. Everything is official Lego pieces, and on the purple cone is a custom star that probably took a lot more work then expected.
If you are looking for something similar, there is an old Lego theme called Fabuland, which shares a lot of concepts. Animal villagers living and working around town.
“It lumbered slobberingly into sight and gropingly squeezed Its gelatinous green immensity through the black doorway… The stars were right again, and what an age-old cult had failed to do by design, a band of innocent sailors had done by accident. After vigintillions of years great Cthulhu was loose again, and ravening for delight.”
— H.P Lovecraft, The Call of Cthulhu
Carl Merriam has created a horrifying Cthulhu Lego MOC. With a whole lot of specialized Lego pieces that one would not normally associate with a build like this. There are Velociraptor pieces, Medusa bodies, and weird tentacle bits. All of these are combined into a huge SNOT style figure. Which is instantly recognizable, and captures the terror of this monster.
A lot of the details really stand out. A lot of Lego builds have problems when viewed up close, but this Cthulhu looks even better when zoomed in. Especially the mouth area.
The other stand out detail of “The Madness from the Sea” is the little Lego steam ship. The simplicity is a great contrast to the much more detailed Cthulhu. It also lends a sense of scale to the figure. This thing is supposed to be monstrously big. But, best of all is that this little detail adds so much to the story of this MOC.
