yes u did..
i'll close the other one in a bit...but yea..
tamagotchi ocean is similar to the regular tamagotchi(the whole case and everything)..its just that the tamas live in the ocean instead of on land
here is a quote from Bandai---
"The Tamagotchi Ocean is approximately 3,720,00 kilometers deep. It is on the world of Tamagotchi. It seems that the Tamagotchi Ocean does not contain salt water but juice and Tamagotchi soda water. The Tamagotchi Ocean floor is like the planet and has beautiful scenery. They have great surfing in the Tamagotchi Ocean. The main staple is Pickles. I have no idea why! In the Tamagotchi Ocean, there are Bugs Island, Summer Winter Island, and Lazy Island."
