There are cartridge slots everywhere. The scanner in the computer core will produce cartridges. Look at it.
Yes, you should have some animal parts (like a skin) to put on the scanner.
There is the lizard skin at the locks. Try the lizard skin on the scanner.
Nice. Now you can go and stick it to every slot. That way you find out to see what they do.
More, you say? Where could you get more animal skins, or patterns?
Do you remember Henna and Tanner (at the Habitat ring) having a hard time selecting from their decorations?
Maybe you could offer them something else.
Do you happen to have already the fine silver gorilla hair?
Well, it is a excuisite interior decor, don't you think? Offer it to Henna at the Habitat ring.
They look nice. They probably contain some animal DNA?
Go and try all of them in the scanner.
You should now have three cartridges: one from a lizard, one from a striped sable and one from a... clown. Try them to the slots.
