How would you reuse these muck buckets?

I have a couple that are cracked and leak, which is ok for dry bedding/manure, and not so great for really urine soaked bedding. Think of it dripping on your leg while you carry it out of the stall. Was trying to think of clever ways to continue to use them where the cracks are not an issue - any ideas?

Maybe use them to container grow something like mint that can spread where you would rather not have it.

Worm tower.

Slice into tree rings to hold water.

Frost protection for plants.

I use similar busted buckets and tubs to grow Taro and some as Black Soldier Fly farms.
