The "Most Dangerous World Imaginable" is a dimension. Rippen has trapped both Brock Zero and Vonnie Zero in there. The only way to get them out of there is by collecting three shards scattered around the multiverse. Penn's MUHU glows green when there is a shard in the world they are in. The shards are used to triangulate the Most Dangerous World Imaginable.
Penn has found all 3 shards
The first shard was found in the episode "Save the Worlds" while Penn was stuck in the Nothingness.
The second shard was found in the episode "The Last Mountain Beast" In the Beast World on a giant mountain
The third shard was found in the episode "The Pirates, the Parrot, the Puzzles, and the Talking Boats" by Maria in the pirate world, but was claimed in the episode "Mr. Rippen"
