As it stands, the ability to set up beartraps is kinda eh as of the update that places random traps around the house. Detective can simply detect the traps and everyone is always looking out for them. So I suggest to give them a bit of a buff, something new to shake up gameplay and encourage strategy for the Neighbor.
There's two conditions for this, depending on what type of weather it is currently.
If it's snowing, like now, anywhere that there's snow actively falling on the ground the Neighbor can place one of his traps there. However, if after placing a trap (or is looking at a already placed trap) the Neighbor presses and holds E he will cover it up in snow. This will prevent Detectio from picking up the trap and it will simply become a lump of snow, becoming harder to see for the normal eye. If it's not snowing, if Neighbor places his trap somewhere outside with grass beneath it. He'll be able to cover up the trap with grass and leaves. This will make the trap harder to see and not pick up on detectio.
It's possible that any neighbor can do it too, but it's mainly for Scary Neighbor.
