Hidden Loot Crates

The Hidden Loot Crates are objects in Bad Piggies, being released in the Custom Contraptions update.

Obtaining
Three crates of random types can be found daily. New crates come in 00:00:00 and are available to 23:59:59. There are 7 types of them:
 * Cardboard (2 items)
 * Glass (3 items)
 * Wood (3 items)
 * Bronze (4 items)
 * Metal(4 items)
 * Marble (5 items)
 * Gold (8 items)

They can be found mainly in the Hidden Loot Crates option, where there are three of them daily and can be found in a level. To ease the find of the crate, the player can watch a video and the level that the crate is located will open and it will be marked in the level's button, or if it isn't unlocked, it will only be marked on the level needed to unlock and the player will go to the section of the crate.

The Icon for where the Loot Crate is located is not precisely where it is, it's an image of the level it's located with a Loot Crate. The Loot Crates are often found in locations where it's almost impossible to get them.

The player needs to hit the crate once to obtain it, which it can only be obtained by Ross, King Pig and the vehicle's Core objects. After the player obtains it, the screen will focus on the crate and the player needs to tap it thrice to open it, giving the items.

The Hidden Loot Crates can also be attracted by the "Magnet" power-up.
