S on Mushroom

Mushrooms are uncountable, but not this. It is a One.

If we think One is little, we are definitely wrong.

Clark is ordinary,  but not when he has the S on his chest.

It needs no phone booth, this mushroom can fly. Alices can find it in their garden, backyard or jungle. 

It will be back to my neighbourhood when it intends to.

This One is superb, because it has a S too.
