Jungle pyramid

Jungle temples or jungle pyramids are structures found in jungles.

Generation
Jungle pyramids generate in jungles and its hills, but not all jungles will have one; they also may generate in bamboo jungles. There is a $1/4$ chance that a jungle will generate without a pyramid.

Structure
Jungle temples consist mainly of cobblestone, mossy cobblestone, and some vines. There are 3 floors.

It is possible to find blocks which generate outside temples, like leaves, which have generated inside, possibly blocking the chests or dispensers, or interrupting the redstone.

Puzzle
On the bottom floor there is a puzzle which consists of 3 levers on 3 chiseled stone bricks connected to a hidden piston trapdoor mechanism. If the combination is entered correctly, a block on the main floor is pulled away, revealing a chest.

Trap
Down the hall from the puzzle, there is another chest. There are two tripwire lines connected to dispensers with 2–14 arrows, hidden behind vines. The first tripwire is in the middle of the hallway, and the second tripwire is around the corner in front of the chest. Walking over the tripwire will trigger the dispenser it is hooked up to. Breaking the tripwire with anything other than shears will also set it off.

Blocks
Jungle pyramids are made of:

The cobblestone stairs will never be mossy.
