Ice Rhino is another one of those mounts that have literally no use compared to bunny, duck, or even train honestly. Due to this I think it would be a good idea to rework it so it and doesn't stay in the dirt.

Wherever the ice Rhino walks a trail of slippery ice follows, this ice allows 0 mobility. This ice will not trip but it will disable movement.
