to get the lol kitty, it is actually very easy you just need to get near the spines platform (right or left, both are the same) at the top so you will see that when you jump you will be helped by the shape of the platform which is like a hill near the spines, but no so close to them, then jump moving to left or right (it dependes) in which platform you are, and just before you start falling you double jump again and there you are in the iceberg, i did it at my first try and basically I can always do it
