Congo is just one of those underrated (and increasingly rare) pins. Enjoy it...the Amy voice isn't nearly as annoying as some people say it is, and "playing ball" with her is my favorite part of the game (aside from the erupting volcano). Speaking of which, throw a Pinbits STTNG shaker motor in there so you can FEEL when the volcano goes off. You can thank me later.

I've got mine pointed at the volcano with a red LED. I installed another one on Amy's hand with a blue spot facing Amy. I've seen them with one or two spots and different orientations. I think it's all up to you!
