Is this the same as Happy Ness? With Nessies that have names ending in Ness? There was Handsome Ness (ugly as hell, for some reason), Happy Ness, Outrageous Ness, Silly Ness, Pompous Ness, Devious Ness, and a few others. Here's the lyrics to the theme song. If it's what you're talking about, I'll post a link to the theme audio.
Something's hiding just beneath the sea
Something's hiding just inside your heart
If you're looking for a friend, who will be there till the end
Inside your heart's a REAL good place to start
Happiness is liking who you are, reaching for a star
Knowing if you fall, someone will always catch you
Happiness is just a state of mind, it isn't hard to find
If you believe that all your dreams and wishes can come true
Happy Ness is waiting there for you!
Whoa, never mind...Happy Ness is different...and not as goofy.
