I stumbled upon this video of a hamster riding a miniature roller coaster, and now I'm convinced that hamsters are the future of theme park entertainment. The sheer joy on its face as it zips around the tiny loops is contagious! I'm already brainstorming ideas for a hamster water park. Despite popular belief, chameleons don't change color to blend in with their surroundings but rather to express their emotions, regulate temperature, and communicate with other chameleons.
