Froggies and Froglights

Ever since the addition of the froggies and their lights, a couple of biomes have been added that I believe should also have a corresponding  frog and froglight. Take the sulfur caves, this could give a red and yellow frog and have a red/maroon froglight associated with it, this would also open the gate for other underground frog/froglight variants if you wanted. I truly believe the game would benefit from atleast one new frog and froglight to grow the frog family and add to the coloured light blocks.
