Den Den MushiEdit
These are the odd "phone snails" that are used throughout the series. In the english versions, they are called Transponder Snails. They come in a variety of colors and shapes and have multiple functions. The snails act as a number of devices including: rotary phones, fax machines (Which in the 4Kids version is implied to be their rear end as Nezumi says "I'll send you a picture, sorry (Talking to his snail), turn around"), and cellular wrist watch devices. Den Den Mushi are able to communicate through radio waves. This is proven when Smoker catches a conversation between Sanji and Mr. 0 on his Black Den Den Mushi. When they are used, the snails speak in sync with the caller's voice, as well as sometimes imitating the facial expressions of the caller. When not in use, the Den Den Mushi are usually inert, either sleeping or in a dazed state. They first appeared in Chapter 94 and Episode 43.
Other types of Den Den Mushi include:
- Black Den Den Mushi
- Baby Den Den Mushi
- Golden Den Den Mushi
- Silver Den Den Mushi
- Surveillance Den Den Mushi
- Visual Den Den Mushi
- White Den Den Mushi
Sea Kings are mythical sea creatures in the anime and manga One Piece, which are generally much larger than normal sea creatures. They are found in great numbers along the Calm Belt around the Grand Line, although in rare occasions they can be found in other places throughout the world.
The size of the sea kings are huge as it shows in the picture to the right, even the Straw Hat pirates' Going Merry, which is on the nose of the black and white Sea King, is hardly even visible. Some of these same Sea Kings make another appearance when stopping Noah. It is not known if these are the same Sea Kings we saw at the entrance to the Grand Line, but they do bare a striking resemblance.
Sea Kings make trade and travel difficult for anyone trying to cross the water where they are found. Cases have arisen where some islands in the Grand Line close to the edge of the Calm belt have ended up getting almost completely cut off from the rest of the world. In Water 7 and its surrounding islands, this led to the eventual creation of the Sea Train as a means to travel safely to and from each of its surrounding islands.
Sea Kings are serpent-like in appearance however they vary from one Sea King to another in exact appearance along with their size. Only the strongest of ships or captains can take on a Sea King. Most other creatures in the ocean fear the Sea Kings and confrontation with one by all but a few humans is inadvisable. Many characters such as Franky see the act of killing one a sign of strength and achievement. The Sea Kings are type C creatures. They first appeared in Chapter 1 and Episode 4.
News Coo (ニュース・クー Nyūsu Kū?) are medium-sized seagulls that deliver newspapers and wanted posters around the world. They wear hats to signify their employment and carry bags over their shoulders, just like a paperboy. According to Gloriosa, they do not deliver newspapers to the Calm Belt. The first News Coo appeared delivering a newspaper to Nami.
Panda Shark (パンサメ Pansame?) is a shark with markings that make it look like a panda. Unlike other sharks, its teeth are not razor sharp. One panda shark had carried Yosaku to the Baratie to tell Luffy and Sanji about their progress on following Nami's trail. Another one is seen in Hatchan's mini-story. It was saved from a hook pierced through his nose. As a reward, it gives the Fishman a ring. The panda shark made its first appearance when one carried Yosaku back to Baratie.
Island Whales (アイランドクジラ Airando Kujira?) are the largest whale species in the One Piece world. They resemble the real world sperm whales and come from West Blue. They are highly intelligent, as seen with Laboon being able to understand complex human dialogues between several people, as well as reading their body language. Being social creatures, they normally swim together with other island whales in pods but may adopt another family (e.g., Laboon adopted a pirate ship as his pod and swam with them). The first that appeared was Laboon, in Chapter 102 and Episode 62. A large pod of island whales was seen right at the beginning in the New World.
