Mondo Grass Question

I am the one who has been stressing over finding a way for the toads
to get out of the pond easier.
My neighbor has LOTS of mondo grass i am welcome to. If i plant it
where it hangs over and slightly in the water, will that harm
anything? As far as dead plant matter, i will clean the pond in
about 6 months. If there is no harm here, can the toads latch on the
climb out by this method? It would also make baby critter cover.

What do you think?
