Pest

Having passed the floor of the Temple of,Something, you get back into the elevator,but you don’t notice how Pest is running behind you and literally pushes you, saying
–From the road ビッチ！
with a dissatisfied expression on his face, he enters the elevator and crosses his arms over his chest, turning his head away, not wanting to look at you.

Pest is standoffish from the other NPCs. He is a loner and doesn't wish to make friends, denying the fact whenever an NPC calls him one. He is easily annoyed, is straight forward, and will often steal items and lie about it when asked if he knows where they've gone. Pest has a tendency to insult whatever NPC he is talking to in Japanese so they won't understand what he's saying.

Pest has a chance to appear on The Subway floor. Pest enters the elevator saying "こんにちは ! 今日は素敵な日です。", which roughly translates to "Hello! Today is a lovely day". He can steal coins if a player is close enough to him. The amount of coins depends on the victim's coin amount, with Pest being able to steal up to 5-10 coins.

He climbs out of the elevator to steal the ruby from the Temple of, Something floor. He also exits the elevator on the Cardboard Mansion and Happy Home Party floors.
