Quoted from BozoTheClown:
I installed something like 4 fire bulbs in mine and it looks amazing.
I did a light strip and a couple fire bulbs also which helped a lot to bring it to life. I believe Comet sold those, their matrix system is plug and play, very easy
A shaker would be cool for the volcano. Never tried to fit one but that game might be worth it
I so much love my Congo, it is a forever game
