Bug catching
Face a bug, get close and press E to swing your net. What's out depends on the hour, the weather and the place.
There's no aiming screen: face the bug, get close and swing. A better net reaches further, startles bugs less and can catch two at once. Which bugs are out depends on the hour, weather and place, so the same spot changes through the day.
Sell what you catch to Mabel, give one of each to the Collection, or keep three of a kind for Tuck on a Monday or Thursday.
