Google translates the Spanish as follows:
"This is translated with a translator so it may not be very effective. So I say the error is in Spanish. That when you fall in a block you fall depending on how to stay docked in it and this is also true of animal bone mobs left alone inside the block and not leave unless you hit is more common than in leaves are docked jungle."
I think "docked" is the wrong word here. While I'm not certain exactly what the reporter means, my guess is that this partly refers to animals spawning inside leaves in jungles. They don't leave the block unless the block is destroyed or you hit them causing them to jump up out of the leaf block.
Possibly a duplicate of MC-816.
