So they piss on people as well! Precious! :)

Make them smart enough to water the plants! :)

Finding it's own "food" would be highly important for any type of robot I
would set loose in the world with the desire to survive.
I can't help but think how cool it would be to make a robot smart enough to
wonder around the world, avoid being caught, but be smart enough to find
electrical outlets to charge itself with. :)
The same would be cool if the "fish" were smart enough to swim down and
find outlets to plug into if you couldn't get enough power from sunlight so
that you wouldn't have to install special power stations for them to dock
at.

Well, in a large mall, one with 100+ stores, that's just 1 fish per store
on average - not all that crowded - just very "busy" with fish. If you
only had something like 10 fish, people would have to run around looking
for them before they would find one. It would all depend on how big the
location was and how big the fish had to be to carry their hardware. Just
one would still be cool.
