Decapo-chan is a strange crab-like creature that can travel the world by crawling and flying. On both its arms are two "pincers" resembling claws, but they do not hurt at all when they pinch.

​

During certain periods of the day, it can change its appearance to resemble a sunset and the night sky.
Sometimes this counts as means of camouflage as well.

「でかぽちゃん」はカニに見えるな生き物だけど...
なんと...空を飛べます。つま先は羽みたいな感覚だから積まれると痛くない。
夜になるとたまに色が変わったりします。
