Carry companion & Shrink Object - any cool uses you can think of?

This is a bit niche, since carry companion already takes care of most situations of moving an animal through a populated area or carrying a beast of burden through a dungeon.

But what if a palm-sized figurine is still a little too big? What if you could shrink that to something capable of fitting in your ear, or nose (or other orifice)?

What shenanigans can you think of with these two spells?
