I think in any non-Genocide Route, Frisk just bumps into monsters by accident, which is why there is a "!". Frisk is surprised because he didn't expect to run into them.

In the Genocide Route however, Frisk is actively seeking them out to kill them, possibly by "calling out for them". The ":)" that appears is because Frisk found what he was looking for, and when the area is exhausted of monsters, Frisk calls out for more, but "nobody came".
