Veranda

The Veranda is the first location of the Treacherous Mansion during the events of Luigi's Mansion: Dark Moon.

During the events of Front-Door Key, Luigi is sent to the gate near the mansion. Here, he can see the ravine and cliff the mansion is by. He has to cross a few sets of rafters, but they break once he gets near the entrance.

When Luigi gets near the entrance, he tries to use the key to open the main door, but the Polterpup steals it before he gets a chance to open it, making him chase it down the well near here. He can look through the windows here or shine the gargoyles. The windows can show a brief image of the Front Entrance or the West Gallery, depending on which side Luigi is on, and southeast of the well, there is a hole that he can peek into to get a glimpse of the Guard Tunnel.

During Double Trouble, the Veranda is where Luigi must use the key to open the door to get in. He can no longer go back to the gate or the basement of the mansion due to the rafters being broken, and the well's red ball is down.

The Veranda is irrelevant for the rest of the missions until Terrifying Invasion, where Luigi can now revisit the well, but he still cannot go back to the gate.
