Hi! Good to see a new player around.
I think the Evo Ship is a little less developed than other metarooms, and may not have a door, portal or teleporter included for creatures to use by themselves. A short list of agents (addons) to supplement/enhance the Evo Ship can be seen at the Creatures.wiki, including ways to populate it with food.
If you'd prefer to try a more rounded metaroom, the list on Eemfoo.org has commentary on how useful the rooms are, with download links.
Thanks for the help! :>
I managed to get a smaller room like you said, those agents linked from Evo Room worked great!
