Gyroid from Animal Crossing. I take no credit for design like all my other ones, but this was a straightforward build. Except connecting the two...Aheh. I should have worked top to bottom <_<. Oh well. PM for file.
The Wii version is by far my favorite. But they're all so different which makes them equally fun. Nintendo should make an Animal Crossing version where YOU get to be an animal and you pick the species (sheep, goat, bird, cat etc.) of your player and design their markings. ^^ That would be so cool!
