\begin{tikzpicture}[pi cloud/.style={draw,cloud,cloud puffs=4,cloud puff

\node[pi cloud,path picture={\node[anchor=north east]

Which changes? I just defined a pi cloud style and added a label via path picture. You could also add the label to the definition of the style:
\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{shapes.symbols}
\begin{document}
\begin{tikzpicture}[pi cloud with label/.style={draw,cloud,cloud puffs=4,cloud puff
arc=31.4,align=center,label={[anchor=north]above:$\pi$},
path picture={\node[anchor=north east]
at (path picture bounding box.north east){#1};
}}]
\node[pi cloud with label=t]{text here};

@manooooh Well, as I said it is a pi cloud. So if I add pi at the right places:
\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{shapes.symbols}
\begin{document}

\begin{tikzpicture}
\node (2) at (4,0) [shape=cloud,cloud puffs=4,cloud puff arc=40,draw,
text width=2.7cm,align=center,label={[anchor=north]above:$2$},
path picture={\node[anchor=north east,text width=3.14mm,align=left,text
height=3.14ex]
at (path picture bounding box.north east){t};}] {EXAMPLE\\EXAMPLE\\EXAMPLE};
\end{tikzpicture}
