Airlock
From Space Tree Wiki
Space Tree's Ship features an airlock, which is used to get rid of unwanted things. The airlock has been given several upgrades during the course of the show.
In Space Jam, the airlock features handprint security to open the sliding glass door, which needs Allon's handprint to open it. There is also a switch to jettison the contents of the airlock, as seen on the image. Above the door is a sign that say "AIRLOCK (because this is a spaceship)". In this episode, the Commander tricked Allon to going into the airlock, he used Allon's ripped-off arm to open it, in order to hide from Space Tree, but instead ejected him into space, where he "would hopefully die".
In Space Vision, Allon is ejected into space once again, but this time by Space Tree, who said his costume sucked, he was late for Halloween and that Halloween doesn't even exist (three strikes). However, instead of flipping a switch, Space Tree pulls a lever to activate it.
The airlock takes on a slightly different appearance in Amanolla Family Reunion. It now has one release button labelled "BLASTOFF", a readout feed, and the sign has been altered by Professor Clerman to say "ALLON'S ROOM (NOT AIRLOCK) ship)". Apparently the airlock can only be released once a week. Professor Clerman attempted to use the airlock to dispose of Allon's entire family. However, when he pressed the release button an Airsock-error message came up and he couldn't get it to work, so he simply boarded them up inside.
According to the Narrator, Allon's family continue to live in the airlock for three more generations until space is destroyed by Anti Space Terrorists. However, in Episode 49 the ship blows up...
