Spark All The Key And All Of Them will Not Have ctype!
found it its on top of the second key the very tippy top of it
oh. yeah. it is key 2. gg
EZ its in key 2 X:105 Y:231 just do this: !set type gold snow and wait until all snow melts, the one that turns into water is the one, the rest turns to gold as its ctype is set to gold :)
The key 2. Use property tool and convert gold's type to lava and cool it. Then you can see the 1 pixel of stone on the top of the key 2.
WAIT..... WAIT WAIT WAIT WAIT WAIT. is it KEY 4?
