Blowfish

I saw a little blowfish,
Just swimming in the sea.
He wasn't much to look at, though,
Until he looked at me.

He thought that I would eat him, and
Although it wasn't true,
He blew himself like a balloon,
And grew, and grew, and grew.

He now was much, much larger,
And scary looking too.
And I will end this poem here,
As now my story's through.
