Ajax加载太慢了吗？

I am working on a puzzle game and everytime I load my webpage it takes a while for everything to load. I tried putting a pause until the ajax is loaded but that doesn't seem to fix it. I just want it to load more smoothly. Here is my jsfiddle :

It's not working properly on there but it demonstrates my problem anyways.

Can anyone fix my code for me?

Here is my webpage with the puzzle:

var plant = "";

$.when($.ajax({"url":"http://beta.botanicalapp.com/api/v1/plants/?photo=true"}))
.done(function(fullData){
    (function(){
        var rand = Math.floor(Math.random()*fullData.length)
        while (rand == 3) {
            rand = Math.floor(Math.random()*fullData.length)
        }
        plant = fullData[rand].plant.image_default.url;
    })()
    startGame();
});
