Get two quarks together and you get mesons. Three quarks together and they form baryons, which include many of the particles that we are most familiar with, such as protons and neutrons. The combination of three quarks also produces much more esoteric particles such as Ξ and Σ. But if you get four or five quarks together and you get some really unusual particles. The initial hints of tetra- and pentaquarks didn't stand up to further examination, but more recent experiments including BELLE and LHCb have firmly established their existence.
