1. Download the bricks at
https://www.dropbox.com/s/tcukzhmpiq8q3om/Squideeys%20Bricks.zip?dl=02. Extract the zip to your desktop
3. Go to your Blockland folder, and navigate to the shapes folder through Blockland>Base>Data>Shapes
4. Drag the contents from the zip folder into the shapes folder and press replace
5. Set all the files you added in to the shape folder to Read-Only, or else it will not work. To do this, right click the image, click properties, go to the General tab, and at the bottom of it should be Attributes, there you can set it to Read-Only.
(I'd recommend getting a backup of your previous brick textures just in case you need them.)
