So, I'm pretty sure all the games in the game room's images are actual on-site items right? and Spectrail has this cool rainbow/spectrum thing (it's also at the top of the high score page here) and I tried looking on subetalodge for items with spectrum or rainbow in the name, but I didn't see it.. does anyone happen to know which item it is?

- I don't think it's a real item. I don't remember ever seeing it around, and the image url isn't the same as real items:

Item images are all img.subeta.net/items/image_name.gif
