Pineco is a blue pinecone-like Pokémon with red eyes and no visible limbs. It seem to have a single horn on top of its head which is supposedly its stem.
Gender differences
None.
Special abilities
Pineco has the ability to explode, as evidenced by its ability to learn Selfdestruct and Explosion.
Behavior
Pineco likes to make its shell thicker by adding layers of tree bark. To do so, it spits out a fluid, which hardens when it touches air, to glue the tree bark to its body. The additional weight does not bother it.
Pineco patiently hangs from a tree branch, in wait for flying insect prey to come near. It does not move much on its own, but if Pineco is disturbed when eating by someone shaking the tree, it drops down to the ground and explodes with no warning.

Origin
Pineco is based on a bagworm living in a pine cone. Its metallic appearance and ability to explode also links to a hand grenade. In addition to its possible relation to weaponry, its ability to learn Spikes may be a reference to caltrops.
