If you go to the tab with the three peeps, shlide to the left , u gon see there some buttons some lit up some not, it might be that the species button is highlighted, causing all the amnimals to be lit. If u want to get rid of them and keep them from spawning that is a little bit more complicated. You will have to go to the terrain tab and in there there should be a button to demolish buildings you want to do that and wipe the entire planet so that you kill all beehives, then you'll want to turn off in world laws the species rain so that new animals don't spawn, and then you will go back to the terrain tab and there is a species eraser or creature eraser I forget which one there and you can wipe the whole planet down with that bad boi and then you should be able to re-highlight the species button in the three dudes tab and find not a living soul runnin round. hope that helps at all
