The X(3872) Meson and "Exotic" Spectroscopy at CDF II

A spate of remarkable new hadrons reported in 2003 may lead to unequivocal proof of states beyond conventional $q\bar{q}$ and $qqq$ structure. Claimed baryonic states Theta+, Phi, and Theta^0_c would consist of five quarks, and new D_{sJ}-states and/or X(3872) might contain four quarks. I review efforts to search for and study this ``new'' spectroscopy in pbarp-collisions with the CDF II detector. Pentaquark searches are negative, and no evidence for exotic analogs of D_{sJ}-states was found. CDF has confirmed the X(3872). My main focus is the production and decay properties of the X(3872), and its possible interpretations.
