Build a shark using digitized versions of preexisting LEGO blocks. Decide what kind of LEGO blocks you want to use. Sharks are long and bow outward in the center and are mostly gray colored. Do not forget about the small, beady black eyes and fins. All of the blocks are located in the right column of the program. To select a block, hold down the left mouse button while clicking on the block, then drag the block to the center. Continue to do this until the shark is built.
