On a rainy day, Blue wants to do something musical. As it starts to rain, Blue and Steve discover that the raindrops sound like music. Blue decides she would like to do something musical, and they play Blue's Clues to figure out what Blue wants to do on this rainy day.
In one version, Blue enjoys splashing outside in her rain boots, jumping in puddles, and even seeing a rainbow, showing that she likes to play outside despite the rain.
In the interactive episodes, Blue and Josh also look for the right rainy day clothes like rain boots, a waterproof jacket, and an umbrella to get ready to play outside in the rain.
Overall, Blue's idea of what to do on a rainy day involves enjoying the rain musically or playing outside with proper rain gear and having fun with puddles and raindrops. This reflects a cheerful, playful approach to a rainy day rather than staying indoors.
