How to unlock the Such Bad Children achievement in The Cave - Definitive Guide
There are two possible ways of getting this achievement!
1. When you have gained the lockpick, you have to open the little room on the right side (I think it's between floors 2 and 3), where there is an open fire, a comfortable chair and a book shelf. Just press X two times in front of the shelf, thus breaking it, getting the achievement and getting another artwork.
2. You could also get it by jumping on the parents' bed (2nd floor, right by the dumbwaiter, where you find the chamber pot) (thanks to SuperTigerWoods for his tip on this one)
While in the twins house there are technically 2 ways to obtain this trophy.
Way 1
When getting the chamberpot from your parent's bedroom, jump on the bed three times.
Way 2
After obtaining the skeleton key, go to the right inside to the living room where there are two book shelves. Press square three times while standing in front of the right hand shelf. There is also a cave painting behind this shelf.
This trophy can only be earned in the Twins’ story.
This trophy is extremely simple. Once you enter the Parent’s Bedroom in the Twins’ level, jump on the bed three times and it will break, earning you this trophy.
The following video shows how to earn this trophy. Thanks to Admiral Vic:
You can also earn this trophy by knocking over the bookcase in the living room, behind which is a Cave Painting. Thanks to Dancing Mad for confirming this.
Required: Twins
There are two ways of getting this achievement. You can ride the dumb-waiter to the twins parents bedroom and jump on the bed two or three times until it breaks. Or, when you get the lockpick, you can break the shelf in the room with the open fire (press twice). Either way works fine.

By the way, there is a rock painting behind the closet!
