The player will be given the command to find the block that contains the required word sound. These fit into a 2X2 puzzle and when the player completes said puzzle, they can proceed to the next level. The third level requires the player to complete the word shown. When the correct answer is given a random character or creature pops out of the scenery praising the player.
