The Maternal Sculpture is a treasure in Pikmin 2. It is really a baby bottle top. It is located on sublevel 9 of the Cavern of Chaos. Poison is found here, and there are few enemies, all of them flying: a Bumbling Snitchbug and a couple of Careening Dirigibugs. The treasure is easily within view, as is the sublevel's other treasure, the Wiggle Noggin.
