Octopus's Bathroom

You may have heard of an octopus's garden, thanks to The Beatles, but are you familiar with an octopus's bathroom? As you can see, the miniature octopus hanging out in the bathtub of my dollhouse is camouflaging itself, changing both the color and texture of its skin to match the log. (For a short but fascinating read on so-called chameleons of the sea, check out this article.)         

For the log, I first wound a few yards of Brown Sheep Lamb's Pride Worsted yarn in the color Seafoam around a trimmed paper towel roll. Next, with size US 5 needles, I knitted a simple garter stitch sea mat next to which the octopus would rest. Finally, I glued some seashells to the opposite end of the log.    

For the octopus, I slightly modified Marie M's pattern, using the same size knitting needles and yarn. The entire piece is knitted flat with minimal seaming.
