Binacle evolves into Barbaracle starting at level 39. This evolution involves the two Binacle combining and multiplying into seven individual Binacle units that form Barbaracle. Binacle is a dual-type Rock/Water Pokémon introduced in Generation VI and typically lives in pairs on a single gray rock, cooperating to survive. Once it reaches level 39, it evolves into Barbaracle, which has multiple limbs each with independent movement but usually following the head's orders.
