toys for my mice?

I'm starting to keep all the mice my snake doesn't eat. (Refuses to sometimes..) So i'm making a home for all the lucky mice that live.
I want them to be eating the best meals, drinking the finest water, and I want them to have a little pool. Nothing is too small for these mice.
Put it in better words, they will be living better then I do.

But what is all that, if they don't have any toys? I am getting them a running wheel, but that seems boring after awhile. I want some cool toys for em.
Any ideas? They will be living in a tank for now, While I construct em a super hotel. - this hotel will be awesome.

-Jingly cat toys, my ASFs love to knock them around.
-bird toys (love them)
-Take a toilet paper roll and put treats inside. Cover with paper and tie ends so they have to chew through to get treats!

Mice and rats are a huge fan of tubes and hides.
But honestly, they will live for their wheels. Most of the time they don't want to do anything else. haha.

Yep tubes to hide wheels to run stuff to chew! The pool may end up being more of a toilet tho so be sure it's easy to remove an clean.
