This is a great little song. Wouldn't it have been cool if the B-52s, circa 1980, had covered it? Would have been right up their alley, too. This was the one of the first Japanese cartoons I ever remember seeing, mostly because of the pendant.
Since Marine Boy has been released on MOD home DVD, could the Prince be far behind? That would be really cool if so. At least most of the episodes are available on Hulu to watch now.
