Space Weaver is broken and it needs yarn to work.
By the way, have you tried the runaway train mission yet?
Well, then you have yarn ? .
You should do the wave during the train mission.
Give the yarn to Space Weaver.
That Space Weaver is quite picky. Could you use some kind of tool to make a spindle out of the yarn mess?
Like the fork that has done that stuff with the spaghetti earlier ? .
You can find the fork at the control room. There is a bowl on the counter.
Use the fork on the yarn mess and then give that to Space Weaver.
