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 have one; they also may generate in bamboo jungles. There is a $1/4$ chance for a jungle to 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 that normally generate outside temples (like leaves) appearing inside, possibly blocking the chests or dispensers, or interrupting the redstone.

Puzzle
On the bottom floor there is a puzzle consisting 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 triggers the dispenser attached to it. Breaking the tripwire with anything other than shears also triggers it.

Blocks
Jungle pyramids are made of:

The cobblestone stairs will never be mossy.
