Pixelmator's Pixel Tool Not Available

This is probably a really stupid question, but I can't seem to find an answer anywhere. I want to use the pixel tool in Pixelmator, but I can't find it. Below is a picture of my toolbar. Is there something I'm missing?

Pixel Tool in Pixelmator

You need to manually add the Pixel Tool to the Tools palette first.

You can add it there manually by choosing Pixelmator > Preferences > Tools > Painting. Then simply drag it onto the Tools palette to place it there.
