Guujouhe meaning

I'm trying to translate a children's book for the kids I work with before I leave. I'm stuck on one page! I have the rest of it besides the part after "ryuu" on the third line: https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-xpf1/t31.0-8/1103889...

When I try to translate it I came out with Guujouhe which isn't even a word. I'm clearly reading it wrong, but how!?

Because proper noun is hard to understand.
"Ryuuguujou" is the name of fabulous palace meaning "Dragon's Palace".
By the way, "Guujou" is changed from "Kyuujou" means "Imperial Palace". Both are the same in Kanji.

The word "Ryuguujou" consists of kanji for "dragon," "palace," "castle," and is supposed to be a palace under the sea, where the sea animals gather, with a lord and his wife.

I don't know if there is a fixed English phrase for it, but it is something like the Palace of the Dragon (King) of the Sea. You would want to be sure to add "the Sea," to make sure it is understood that it is at the bottom of the ocean.

You can understand the background, simply by searching 'Urashima Tarō' in Wikipedia.

Every Japanese child knows what a "Ryugu-jo" is, but I doubt that any of them are aware that it has anything to do with dragons or that the kanji version gives us the meaning of "palace."

The explanation is all written in the story itself. The guy is led undersea, and there's these pretty girls and the feast in this big beautiful building. That's all the kids need.

They can find out for themselves about dragons and palaces once they get old enough to look up dictionaries. To the kids in Japan, "Ryugu-jo" is always a mysterious word that they only see in the story of Urashima Taro. I wouldn't want to spoil that for the non-Japanese readers by translating it to a more practical word :)
