Stuck behind a heavy cell door, Yetshi has no more option but use his special air ability to get big enough to destroy the door, or even walls.

Yetshi was normally supposed to stop growing at the end of the fifth page, but I decided to made him a bit bigger a few months after (which explains the different art style). I never ended it, but it came back in 2015, as a remake named "Jailbreak".
