Pacman frog

[Lija]

I also mixed some moss into his soil to make his substrate seem more like what it would be like in the wild so I hope he likes that.

that is not a good idea, moss if ingested posses high impaction risk.

Lija is definitely right, moss can be very dangerous and often fatal if ingested.

If your frog is even half the hunter that my juvenile bullfrog is, he may accidentally swallow some moss.

It's better for him to have large plants to hide by than a partially greenish and also potentially dangerous substrate.
