In the vast ocean, there are two fishy friends who couldn't be more different: the chill Sunfish and the thrilling Moonfish! The Sunfish is like a giant, grumpy pancake that just floats around, eating jellyfish and getting a suntan to warm up because it's cold-blooded. But the Moonfish? It's a speedy, colorful disco ball that flaps its fins like crazy, hunts squid in the deep cold, and is actually warm-blooded, just like you! It’s like one is napping on the couch and the other is at a dance party. Learn more!
