Poppystar should be a thing

Instead of the typical hammer, it can be an oversized microphone, complete with slightly-toned-down feedback noises when she hits something.

Her voice lines could shift slightly in volume if she's singing close to the mic.

If she recalls next to ahri, ahri's recall animation would be slightly louder (teammates could hear it from farther away, or something)

Just a fun thought.

OH, just thought of something. When she ults someone, you'd hear them scream as they fly away.
