Did you know that squirrels have a special way to talk to each other? When they flick their tails quickly, it means they want to tell their friends something important! It's like waving their hands to say, 'Look out!' or 'Be careful!' Squirrels use their tails to help their friends know when something might be wrong or if they need to be safe. Just like when you might tell your friend to watch out for something, squirrels do the same with their tails!
