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.
