A Fangosaurus is a Creature that appears in Adventure and it doesn't exist. It is green, scary horns, an unabrow, a big orange nose and is the same size as bigfoot.
Little Miss Naughty took Mr. Noisy and Mr. Stubborn down into the caves to find one. Miss Naughty fools the two. A real Fangosaurus soon appears and attacks Miss Naughty like a ball. Mr. Noisy sounds his megaphone and it runs away and makes a hole in the wall to fresh air.
