Snakes And Jungle Temple Stuff

i think jungle temples are a bit boring,so i think it should have a trap that when you open the trapped chest, the floor retreats leaving you falling in a pit filled with none other than snakes Indiana Jones Style...

But there is something even better in my idea... the addition of travertine... a stone that will replace the cobblestone of the temple,but why this, because if you create the chieseled version , a snake pattern appears on it and maybe the block could be poisonous,i don't know
