Marsupilami

Hector and the Marsus are on the hunt for frogs for Hector's terrarium. A meteorite falls from the sky. When they arrive at the point of impact, Hector realizes that it is some kind of satellite. He hits it with a stick, the satellite opens and orange foam oozes out. He takes a sample of it to show Aunt Diana because he thinks it's something from far away. Of course, Diana doesn't believe his science fiction story, but she promises to take a close look at the foam the next morning. In the morning the foam has already grown over half the camp. Diana examines it and finds that the components of the foam are all from Earth.
