Unlike previous games, they can appear in any encounter slot.
If you switch the encounter type to "swarm" on the main window, you'll see that the encounter slots will show up as "swarm" instead of the regular one, which indicates that you'll find a swarm Pokemon for that particular frame. --- YOU WANT SOME FUNERAL TO GO WITH THAT CAKE? i'm depending on a generator just to breathe in air
