Binacle is a two-headed barnacle-based Pokémon. Its two heads also serve as its hands, as it has sharp yellowish claw-like features atop its heads. Its heads are attached to a grey rock by orange and white striped tentacles. Each of Binacle's heads are brown in color with sulky expressions on their faces.
Binacle seems to be an ill-tempered Pokémon, like Dodrio. Its two heads sometimes quarrel, and often a head will move to a different rock when fights break out.
