I found a new enemy in JJ2!
It looks like a pillow and it behaves like a spark.

To use it:

1. Open JCS.INI
2. Find the following line:
253=EMPTY |+| |DON'T |USE

3. Replace it with:
253=Pillow |-|Enemy |Pillow |Enemy

4. Save and run JCS
5. Create a new event and select "Pillow" under "Enemies" and "Bad guys".
