In Pikmin: Dual Worlds
The Teardrop Aristocrab is quite an unusual species of Onionshell. It has two arms, one with a claw for grabbing, and one with no claw for crushing. The crushing arm is shaped like a Prince Rupert's Drop, significantly increasing it's durability, making it so that the only way to destroy it is to throw a Rock Pikmin at the very location where it joins to the body. It can regenerate this lack of a claw in minutes in order to defend itself. It can grab three Pikmin at once to eat them in it's non-dominant claw, and can spew bubbles from it's mouth.
