Dolphin Shows can only be put on if you are asked by either Hariyako, or Finley. Talk to Hariyako, and after she is done talking to you, there should be a big blue button on the bottom of your screen that says "DOLPHIN SHOW REQUESTS"
Yes endless ocean blue world is out.
Get the Medal in blue Hall.
To move the tree branch in endless ocean, you need to use the river dolphin. These can be seen in the temple in cortica river.
when you go up to the dolphin you click on it and it will show you the name of the dolphin. i believe you have to come back the next day to get the 2nd part of the dolphin information and that i think is how you befriend it.
To raise your dolphin's level in endless ocean, you simply have to work with it, teach it tricks, and feed it from time to time. It takes a LOT of time.(trust me I feel your pain.) Also, swimming with it wherever you go helps.

It is endless... there is no back, there is no front, therefore there is no middle, therefore it doesn't exist, and the endless world never began...
