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.
Pineco lives in trees.
Pineco eat flying insect prey.
