```
if (skin_var == 1) {
        skin = "%kraken";

        skin_var = 2;
    }
    if (skin_var == 2) {
        // this won't activate
        skin = "%mercury";

        skin_var = 3;
    }
    if (skin_var == 3) {
        skin = "%shark";

        skin_var = 4;
    }
    if (skin_var == 4) {
        // this won't activate either
        skin = "%banana";

        skin_var = 5;
    }
    if (skin_var == 5) {
        skin = "%nuclear";

        skin_var = 6;
    }
    if (skin_var == 6) {
        skin = "%space_dog";

        skin_var = 7;
    }
    if (skin_var == 7) {
        skin = "%t_rex"

        skin_var = 8;
    }
    if (skin_var == 8) {
        // gets stuck right here
        skin = "%spy"

        skin_var = 1;
    }

```

That's my code above. As you can see by the commented lines, they always don't work or get stuck at some point. Is there an efficient way to do this or a way to fix it? 

I just want to change the skin to something every second forever, and I have used setInterval(); but it only seems to do "%kraken" to "%shark" to "%nuclear" to "%t\_rex" and then it cycles before I added "%spy".
