As of current, you literally can’t do anything with the Guinea Pig decors that you can seem to get in massive amounts. So why not do something worth while with them?

That being in the form of an edible!
Maybe even with a small buff or stat/impression boost like you get with the dove feast?

Being one of those decors that people really never use, it would be nice to see them get some usefulness.

I think it would also be nice to be able to turn them into wearable decors if not edibles.
Examples:
-wristbands
-fluffy tail bands
-Guinea Pig coat specific leg warmers
-fluffy earrings
-faux Guinea Pig fur manes

Or even use them as fur on cape decors. With their coat color variety, there are a multitude of options for wearable decors!
