The baby pineapple is looking more pineapple-like by the day! Technically it's just a bloom at this point - a very bristly bloom! It will soon be covered in purple petals, and then it will be on its way to being a delicious fruit.
I have a total of three pineapple plants that I've grown from pineapple tops. This is the second one. The first one fruited last year, and I grew a third plant from the top of its fruit. I grew the first two plants from the tops of store-bought pineapples. They're surprisingly easy to grow, though they're tender, so they have to spend the winter in the house.
