Waddle fan

A waddle fan is a small device that helps keep little penguins cool. Penguins live in places where it can get very cold, but they also get hot when they move around a lot. The waddle fan is like a little mini-fan that the penguins can carry around with them. It is called a waddle fan because penguins have a special way of walking called a waddle. The fan helps keep them cool by blowing cool air on their faces and bodies. It is powered by batteries and has little blades that spin around to create a breeze. Just like how we use a fan to feel cool on a hot day, the waddle fan helps the penguins stay comfortable and happy.
