Toad I'm talking about the little hole near to a golden plate in middle of the map where they putted some glass on top of it
Ohhhhhh ok I thought you meant they filled the hole up. I don't believe there was even stings when the map first came out which made it incredibly easy to pearl out. They added glass to make it more difficult to pearl out of. Honestly, they should add iron trapdoors above the ladder with a lever that can only be accessed by the outside. It would make the pit a much more fun spot to fight in.
