Tummy time mats to help with crawling?

Does anyone know of any good tummy time mats that have things like mirrors and such on it and that can help with crawling?

I have a piano one by fisher price but its not so much a tummy time mat. It just has a piano at the end for baby to kick and toys above head.

I’ve been using blankets for baby to try to crawl but baby just slips a lot I believe it’s too hard on the Blanket.
