Spaced around the public areas of the station are small glowing yellow buttons about 30cm off the ground. At any time, a Rho-bot can boop her snoot or paw against the button and launch a RFID-tagged portable fuzzy amusement sphere from the nearest concealed launcher cannon. The problem comes when multiple Rho's launch balls at the same time, the can loose track of the tags and some spheres get lost in corners and vents.
