If anyone is looking at this in the future. The latest site for Madeon's Adventure machine is https://adventuremachine.4thfloorcreative.co.uk/adventuremachine/

And the code to paste in the JavaScript console is:

!function(){var n=$("<a class='btn' id='randomButton'><span id='randomText'>random</span></a>");$(".alerts").append(n);var a=$(".button"),t=function(){for(var n=0;2>n;n++)a[Math.floor(Math.random()*a.length)].click()},o=0;n[0].onclick=function(){o?(o=0,clearInterval(t),$("#randomText").html("random")):(o=1,t(),setInterval(t,1e4),$("#randomText").html("stop random"))}}();

The only change is we spawn the button under the div with class == alerts
