Granpa & Zoe: Mission Light

What to do when the light disappears? You have to save the Sun!

That's the challenge Zoja and her grandfather take on. Using the famous Hubble Space Telescope, they expose a malicious teenage alien trying to overshadow the Sun with a cloud of gas. The duo must shut down his destructive machine from the inside. To do this, they have to overcome numerous security measures. Luckily, Zoja and her grandfather know a lot about light and its nature.
