Geocities tends to do that to prevent hotlinking. I fixed the image for her.

The character simulator says this is called "バルーンハット", converted into romaji it means "baruun hatto". Obviously Engrish, thus switch the r with an l and you get "baluun hatto". Sounds like "Balloon Hat", actually when you're looking for "Balloon Hat Ragnarok" @ google, you'll find many matches, but no pictures. :/
But I think when I searched for "バルーンハット", I found the words "baloon hat" somewhere in between the kanji symbols, so I think this hat is called
Balloon Hat.

EDIT: Damn, I forgot the joke:
