Next you'll need to add a caption to your cat. But what should your cat say?
Well, there's a great analysis of LOLCat speak, here
, but this is why the picture has to inspire you.
LOLCat vocabulary does have certain highly frequent memes and words, including: "I'M", "IN", "UR" (your), "INVISIBLE", "HAS" (have), "MAH" (my), "HAI", (hi) and "BUCKET". These are then combined into forms like "IM IN UR FRIDGE, EATING UR FOODS", or "INVISIBLE BICYCLE."
In this case, I saw jumping. I saw bright colors. I saw an attack. I saw.... INVISIBLE PINATA!
Generally LOLCats type in white and in all caps, but there's no fixed rule.
