Kalle Stropp och Grodan Boll på svindlande äventyr

Something strange has been spotted over the tree tops in the forest where Charlie Strap and Froggy Ball live, and Plåt-Niklas quickly builds a monocular to examine it. It turns out to be an emergency signal and the two friends together with Plåt-Niklas and The Parrot set out on an expedition to resque whoever is sending the signal.
