Javascript Question

Animate a grouped/ layered SVG with Snap

With the help of genius @Sphinxxx I managed to create a SVG path animation that consists of three stages; init, click and hover. The variables are neatly created with the help of Snap.svg
See the below Codepen for a working demo:

http://codepen.io/Sphinxxxx/pen/EPzmgO

I want improve on this animation by adding lines that resize depending on the state. Basically what is should look like:

enter image description hereenter image description hereenter image description here

<path d="M33.1,18.2c1.1,3.9-4.3,8.6-10.6,9.3c-5.4,0.6-1.8,6.9-7.1,8.9c-6.7,2.6-9-0.7-8.5-6c0.5-4.6-9.6-6-3.5-12
C6.7,15.3,0.6,10.1,4.9,7c4-2.9,4,7.6,13-4.1c2.7-3.5,11.4-0.1,7.4,8.2C22.4,17.2,31.2,11.6,33.1,18.2z"/>

<line x1="1.9" y1="20.5" x2="33.1" y2="20.5"/>
<line x1="4" y1="13.5" x2="24.9" y2="13.5"/>
<line x1="5.9" y1="27.5" x2="22.5" y2="27.5"/>


How can I group different kinds of SVG stuff (paths and lines) to animate together? Any help is much appriciated!

See my demo, more details on pattern fill site:-

//SVG-snap

    sausRed = "#ff1a29",
    strokeWidth = 3;

//Adjust path positions (recalculate path points) before we use them:
//http://snapsvg.io/docs/#Snap.path.map
var matrix = new Snap.Matrix();
initLangSvg  = Snap.path.map(initLangSvg, matrix.translate(4,7));
hoverLangSvg = Snap.path.map(hoverLangSvg, matrix.translate(1,-1));

var chooseLang = Snap("#chooseLang svg").attr({viewBox:"0,0,40,40", preserveAspectRatio:"xMidYMin"}),
    boundingBox = chooseLang.rect(0, 0, 40, 40).attr({fill: none, stroke: none, strokeWidth: none}),
    outerCircle = chooseLang.path(initLangSvg).attr({fill: "url(#lines)", stroke: sausRed, strokeWidth: strokeWidth}),
    boundingBoxGroup = chooseLang.group(outerCircle, boundingBox);

function chooseLangInit() {
    outerCircle.attr({style: "fill: url(#lines); stroke-width: 3"})
    outerCircle.animate({d: initLangSvg}, 400);
}
function chooseLangHover() {
        outerCircle.attr({style: "fill: url(#lines2); stroke-width: 3"})
    outerCircle.animate({d: hoverLangSvg}, 400);
} 
function chooseLangClick() {
        outerCircle.attr({style: "fill: url(#lines3); stroke-width: 3"})
    outerCircle.animate({d: clickLangSvg}, 400);
}
