if bombchelle is near the vcr/tv, you are on the right place.

the puzzle is logical, even if it taked me 6 hours to find it xD

You will have to use all bots in a certain order to find the path to the freedom xD

What happens if you heat air? What can you do with air that is hotter than the air surrounding it? Think basic physics and flight.

Hint: Again, the grate with the manhole can be closed while Iji and Kelvin is in it.
