Octopus Shocktopus!

An octopus falls from the sky one day. It lands on a roof and there it stays. The village's children quickly make friends with it, even though the adults are wary. But the octopus proves very handy indeed, making a perfect slide, helping out with some painting, and even rescuing a cat stuck in a tree. But just when all the neighbors decide they want an octopus of their very own, it disappears. Where has it gone and will it come back?
