I'm looking for treasure ideas for NESiCA's profile. Anything that references arcade games, especially rhythm games, would be awesome. Stuff to do with the general arcade setting is cool too.

I'm not super familiar with rhythm games, but maybe some of this will help!

In general, you can check out the EPICon sections in the Antique Shop, lots of video game/arcade stuff there!

Maybe the carnival shop for like arcade prizes?

[item=BAM! Sticker] Of several of these items (drum sticks, drum kit, coins) there are multiple versions available! There are probably more rhythm related instruments availble in the Music Shop, a full list of which is available on Subetalodge.
