Title: Create a “baby size” costume stone
A costume stone that lets you be baby sized

Description:
It is currently possible by wearing both Giant and Shrink costume stones at the same time. This, however, is pretty clunky as the effect removes itself in 30 min, and if you get soul linked you have a purple ghost.
I think just having a baby size costume stone would be a better way to do it for us that want to be just a smidge smaller :slight_smile:

Why is this a good idea?
Makes an existing (probably unintended) feature work better :slight_smile:

What risks or downsides does it have?
None that I can think of, other then a flood of baby characters

Additional Info:
If possible, compare with similar features in other games. Include images, mock-ups, or examples.
