Why would the Talking Command Block from Blue Monkey not have a tongue?

In the 'Command Blocks' episode of Blue Monkey's Talking Blocks series, a personified command block is depicted as being able to receive what ever he says he wishes for. In the video, he wishes for a tongue, implying that he already doesn't already have one, before wishing it back away for an inexplicable reason. But why wouldn't he have a tongue, is it supposed to be the same logic that command blocks technically aren't alive at all, is it supposed to be related to how Minecraft characters don't have fingers, or is it a forth wall break?
